Circular walk from Golitha Falls to Trethevy Quoit
  1. Walk out of the entrance to the car park and bear right a short distance along the road to the end of the white line. Cross to the wooden gate and go through the gap to the left of the gatepost if the gate is shut. Keep left at the junction of paths to follow the main (lower) path past the information board and dog bag dispenser. Continue on the path until you reach a junction of paths at a dog waste bin.

    At the Golitha Falls National Nature Reserve, the River Fowey cascades through a pretty valley covered in a mixture of ancient woodland and a beech avenue.

    The name is slightly misleading as there are no major waterfalls but rather a series of cascades and rapids. Once expectations are managed that something rivalling Niagara won't be encountered then it's a pretty spot to unwind and enjoy the riverside scenery and wildlife, and journey back through Cornwall's history from 20th Century china clay and Victorian mining to Celtic times where the last king of Cornwall drowned here in the river.

    In spring, the valley is carpeted with bluebells and in autumn, the trees are vivid colours and there are lots of fungi. In summer, look out for woodland butterflies such as the orange and black silver-washed fritillary; the males are attracted to orange items including car indicators!

  2. Just before the dog bin, take the path to the right leading uphill and follow this through the woods until the path ends in a junction with another path with a post on the right with green signs.

    It is thought that the path running between the raised banks (that you emerge onto at the end of this direction) was once part of the leat that channelled water to a high point ready to power waterwheels below.

    The simplest design for a waterwheel is known as an undershot wheel where the paddles are simply dipped into flowing water. This works well in large rivers where there is a strong current.

    However, in hilly areas with smaller streams (such as Cornwall), the overshot design is more common where the water is delivered via a man-made channel (leat) to the top of the wheel where it flows into buckets on the wheel, turning the wheel through the weight of the water. An overshot design also allowed the mill to be located slightly further away from the main river which had obvious advantages during floods.

  3. From the signpost, follow the stony path leading downhill towards the river (indicated for wheelpit and river access). When you reach the wooden railings, keep left to continue downhill to the water's edge. Then turn left and wind between the boulders alongside the river to reach a clearing with some fallen tree trunks.

    During Victorian times a mine, appropriately named Wheal Victoria, operated in the woodland here. The wheel pit beside the wooden fences contained a 30ft waterwheel and the sunken path running above it was once a leat that carried water to it. The mineshaft is some distance away from the waterwheel so it is thought that power was transmitted mechanically via a system of rods between the two.

  4. From the clearing, continue ahead to follow along the brook on your right. As a wooden footbridge on the left comes into view, make for this.

    The name of the River Fowey is from Fowydh, based on the Cornish word for tree, gwydh, and more specifically beech, fawen.

  5. Turn left before the bridge (don't cross it). Follow the winding path uphill to reach a stone-walled gap leading to a path running along a sunken channel.

    Golitha Falls is pronounced by most (even many Cornish) people as "Gol - eye - tha". However it is pronounced "Goleetha" by the local farmers in the immediate area and this considered the correct pronunciation. It was spelt Galetha in the 19th century and Goletha in 1949 so may have originally been pronounced to rhyme with "let" rather than "leet".

    It is thought that name may derive from an old Cornish word for obstruction, similar to the Welsh word gorlifo meaning "to overflow". Another possibility is the name is based around the Cornish word leth meaning "milk" which could have been used to describe white water on the rapids. The go- prefix means "slight" in Cornish so go-leth-a (literally "little milky place" could mean "small rapids").

  6. Go through the gap, turn right and follow the path along the leat (the sunken channel). Continue on the path along the leat until it ends in a junction of paths with the dog waste bin on your left and a granite block on your right.

    Until recently, a raised pipeline crossed the Fowey valley at Golitha Falls. The pipeline was used to transport china clay slurry from the pit north of St Neot at Parsons Park to the Moorswater works on the edge of Liskeard. The old china clay pit is now used as a reservoir for the public water supply, known as Park Lake.

    At Park Lake a floating pump is used to extract water from the surface of the lake without disturbing clay sediment. Due to the relatively flat profile of the lake, dropping the water level by up to 7 metres requires the pump to be on a floating pontoon 100 metres out from the shore. However, the wet surrounding moorland is able to replenish the water in the pit at several million litres per day.

  7. Turn right past the granite block and cross the bridge to reach the main river. Bear left to head upriver and follow the path to return to the lane.

    The Westcountry Rivers Trust began life in a meeting in a Devon pub in 1994 and was set up as a charity in 1995 to protect and improve the Westcountry's rivers and streams. It was initially a small grassroots charity staffed entirely by volunteers and was then run from the home of its first employee.

    In 2001 an umbrella organisation was set up to coordinate the work of four regional rivers trusts (including the WRT) and is now simply known as the Rivers Trust. The 4 founding members have been joined by another 53 that now cover all of Wales, most of England and some parts of Scotland and Ireland.

  8. Turn right onto the lane and follow it over the bridge to a junction. Turn left in the direction signposted to Bolventor. Follow the lane uphill past one old public footpath sign on the right opposite the cottages on the left. Continue uphill to a gate on the right opposite a telegraph pole on the left (which used to have a public footpath sign but may not yet have been replaced).

    From Golitha Falls to its source on Bodmin Moor, the river Fowey lies within a designated Area of Outstanding Natural Beauty.

    There are 33 regions in England designated Areas Of Outstanding Natural Beauty (AONB) many of which were created at the same time as the National Parks. In fact the AONB status is very similar to that of National Parks.

    There is a single Cornwall AONB which was established in 1959 and is itself subdivided into 12 sections. 11 of these are stretches of the coastline and the 12th is Bodmin Moor.

  9. Go through the gate on the right (it's a Gold public footpath) and follow the track ahead, keeping right at the junction of paths along the track leading down into the valley. Follow the path past a waymark on the left to reach a second waymark on the left with a tree ahead.

    The stones of sloes (and plums, cherries and peaches) contain the compound amygdalin which is metabolised into hydrogen cyanide. Therefore breaking the stones is best avoided when using them in cooking, gin etc.

    In mediaeval times, blackthorn was associated with evil. This may also tie in with the English word "strife" which has Celtic origins. Straif was the name of a letter used in Celtic Ogham script and was originally the word for "sulphur". Some of the other letters in the script corresponded to tree names. In late mediaeval times, a retrospective assignment of trees to the letters in the alphabet used for Ogham that weren't already tree names became popular (sometimes known as the "tree alphabet") and blackthorn was chosen for Straif.

  10. From the waymark, follow the path between the gorse and tree to reach one waymark on the right and continue a little further to reach a second waymark on the right.

    Before the Industrial Revolution, gorse was valued as a fuel for bread ovens and kilns as it burns rapidly, very hot and with little ash. It was in such demand that there were quite strict rules about how much gorse could be cut on common land.

    In more recent times, due to reliance on fossil fuels, this is now out of balance and gorse has increased in rural areas which have been abandoned agriculturally.

  11. Continue ahead on the path through the bracken and into the woods. Follow the path until you reach a stone stile crossing a wall ahead.

    The stream is a tributary of the River Fowey which it joins near Draynes Bridge at the start of the walk. The stream is fed by a number of moorland springs around Common Moor and Higher Gimble.

  12. Cross the stile over the wall and follow the fence on the right to reach the stream. Follow along the stream to reach a gate in the fence ahead.

    If there are sheep in the field and you have a dog, make sure it's securely on its lead (sheep are prone to panic and injuring themselves even if a dog is just being inquisitive). If the sheep start bleating, this means they are scared and they are liable to panic.

    If there are pregnant sheep in the field, be particularly sensitive as a scare can cause a miscarriage. If there are sheep in the field with lambs, avoid approaching them closely, making loud noises or walking between a lamb and its mother, as you may provoke the mother to defend her young.

    Sheep may look cute but if provoked they can cause serious injury (hence the verb "to ram"). Generally, the best plan is to walk quietly along the hedges and they will move away or ignore you.

  13. Go through the gate and follow along the wall on the left, past the gateway, to reach a gap at the top of the fence on the far side of the field.

    Sheep are now farmed pretty much solely for their meat rather than their wool. The reason that you may see scruffy sheep with wool falling off is that due to cheap synthetic (plastic) fibres, demand for wool declined through the late 20th and early 21st centuries resulting in many sheep not being shorn due to the wool price being lower than the cost of the labour to remove it.

  14. Go through the gap and follow the path between the fence and wall to reach a metal kissing gate.

    The hawthorn tree is most often found in hedgerows where it was used to create a barrier for livestock, and in fact haw was the Old English word for "hedge".

  15. Go through the gate and downhill a couple of paces to a track. Bear left to follow the track until you see a waymark on the right. Then make for this.

    Whereas many plants rely mainly on bitter chemicals to avoid being eaten by herbivores, thistles have gone one step further and evolved spikes. Grazing livestock will understandably avoid them which allows them to accumulate in pastureland and become a nuisance. One thistle plant produces thousands of seeds dispersed by the wind which can remain viable in the soil for up to 10 years.

    Plant nutrients like phosphates and nitrates are used to improve the fertility of soils to make crops grow well. These chemicals dissolve easily in water and can wash into rivers where they stimulate the growth of algae. This uses up the oxygen in the water, suffocating the other aquatic life.

    Phosphates are also used in many laundry and dishwashing powders. These cannot be fully removed by the sewage treatment process and the remainder is discharged into rivers, causing serious damage. You can help to reduce this by switching to low or phosphate-free dishwashing and laundry detergents (Ecover brand is particularly good and their dishwasher tablets seem to work amazingly well). Other things to be on the lookout for around the home are waste pipes that go into drains instead of sewers (these don't get any sewage treatment so any phosphates go straight into rivers). It's worth ensuring cesspits/septic tanks are emptied regularly otherwise all kinds of nasty things including phosphates will seep from these through groundwater into rivers.

  16. At the waymark, cross over the stream then follow the wall on the right to a waymarked stile. Cross this and follow the path alongside the stream to reach a final stone stile with a Public Footpath sign.

    Foam on the surface of a river can look like pollution but, as with sea foam, it's normally a natural phenomenon. When water plants such as algae die and decompose, organic matter is released into the water. If the water is agitated, proteins in the water can form a froth, just like whisking egg whites. Plant nutrients entering the water will increase the amount of algae, making foam more likely or prolific so a very foamy river can be an indicator of nitrate or phosphate pollution.

  17. Cross the stile and turn right onto the lane. Follow it until it ends in a T-junction.

    Ferns produce neither flowers nor seeds and rely on the tiny spores for their reproduction which are most commonly distributed by the wind. This allows them to colonise some quite random places such as rocky ledges that heavier seeds might not reach. Since the spores come from just one parent fern, the offspring is a genetic clone.

  18. Turn right and carefully follow the road to reach a Public Footpath on the left just past King Doniert's Stone.

    King Doniert's Stone, located near Golitha Falls, consists of two stone fragments of an ancient memorial cross which is thought might have originally been topped with a wooden cross. It dates from the 9th Century and commemorates the death of Dungarth the King of Cornwall, who drowned in the River Fowey nearby at about the time when the Anglo-Saxons were gaining control of eastern Cornwall. The shorter stone has an Anglo-Saxon inscription which has been translated as "Doniert has asked prayers for his Soul".

    More about King Doniert's Stone from Cornwall Heritage Trust and the Cornish Bird blog.

  19. Climb the stone stile with the metal railing over the wall. Walk along the wall on the left to the semicircular area with King Doniert's Stone then bear right slightly across the field to the gate in the middle of the hedge ahead.

    The Ramblers Association and National Farmers Union suggest some "dos and don'ts" for walkers which we've collated with some info from the local Countryside Access Team.

    Do

    • Stop, look and listen on entering a field. Look out for any animals and watch how they are behaving, particularly bulls or cows with calves
    • Be prepared for farm animals to react to your presence, especially if you have a dog with you.
    • Try to avoid getting between cows and their calves.
    • Move quickly and quietly, and if possible walk around the herd.
    • Keep your dog close and under effective control on a lead around cows and sheep.
    • Remember to close gates behind you when walking through fields containing livestock.
    • If you and your dog feel threatened, work your way to the field boundary and quietly make your way to safety.
    • Report any dangerous incidents to the Cornwall Council Countryside Access Team - phone 0300 1234 202 for emergencies or for non-emergencies use the iWalk Cornwall app to report a footpath issue (via the menu next to the direction on the directions screen).

    Don't

    • If you are threatened by cattle, don't hang onto your dog: let it go to allow the dog to run to safety.
    • Don't put yourself at risk. Find another way around the cattle and rejoin the footpath as soon as possible.
    • Don't panic or run. Most cattle will stop before they reach you. If they follow, just walk on quietly.
  20. Go through the gate and follow the right hedge to a waymarked gateway onto a track, just before the corner of the field.

    King Doniert's Stone and Trethevy Quoit are managed by the Cornwall Heritage Trust.

    The Cornwall Heritage Trust (CHT) is a charity founded in 1985 to preserve and strengthen Cornish heritage. The CHT own some historic structures such as the Treffry Viaduct and also manage a number of state-owned English Heritage sites in Cornwall such as Carn Euny.

    The CHT management of some of the smaller English Heritage sites follows controversy in 1999 when the Revived Cornish Stannary Parliament pressure group removed several English Heritage signs. CHT now manage these in partnership with local communities, Natural England, Historic England and English Heritage.

    As part of the English Heritage partnership, members of the Cornwall Heritage Trust can visit the larger English Heritage sites in Cornwall (Tintagel Castle, Restormel Castle, Launceston Castle, Pendennis Castle, Chysauster etc) free-of-charge. CHT annual membership is therefore quite an economical option for anyone intending to visit multiple English Heritage sites solely in Cornwall. The family membership is particularly good value-for-money.

    More information about the Cornwall Heritage Trust.

  21. Turn right down the track and follow it until it ends at a gate.

    Common knapweed (also known as black knapweed) is most easily recognised by its bright purple thistle-like flowers but without spiky leaves. It's actually a member of the daisy family and is often seen along paths and roadside verges. Other names for the plant include "hardhead" (used in Cornwall in Victorian times) and "loggerhead" due to the sturdy flower heads. "knap" is from the Middle English word for "knob" and consequently another name for the plant is "knobweed".

    It is an important plant for pollinating insects and was rated in the top 5 for most nectar production in a UK plants survey. In terms of plants that produce both nectar and pollen, it is rated as the top producer overall, producing a good amount of each.

    Fossil records indicate that bracken dates back at least 55 million years. By 24 million years ago it had a worldwide distribution and it is now thought to be the most common plant in the world.

  22. Go through the gate and follow the line of the hedge on your left to reach a track on the far side of the yard, leading to the left.

    The word "farm" has the same origins as (e.g. law) "firm". Both words are related to the mediaeval Latin word firma meaning "fixed payment". Its original use in English was to do with contracts and leasing (which is why "to farm out" means "to subcontract"). In fact the word "farm" had no association with food production until the 19th Century. In the 16th Century it began to be applied to leasing of land and the association with farmland developed from this.

  23. Turn left onto the track and follow it until it ends at a pair of double gates onto a lane.

    Goosegrass gets its name from its attractiveness to poultry as a nutritious food. It contains tannins which make it too bitter for humans. The plant is in the same family as coffee and the seeds have been dried and roasted to make a (lower caffeine) coffee substitute.

  24. Climb the stone stile to the right of the gates and turn left onto the road. Walk a short distance until you see a stile on the right with a public footpath sign opposite a telegraph pole on the left.
  25. Cross the stile on the right and follow the right hedge, crossing the track at the far side of the field to a gateway in the far hedge leading ahead.

    Watch out for the holly bush as you cross the stile.

    The association of holly with winter celebrations predates Christianity: druids were known to use holly wreaths which, it is likely with some discomfort, they wore on their heads.

    Holly was known in Cornwall as the holm (bush) and is the origin of the Holmbush area of St Austell and Holmbush Mine in Kelly Bray.

  26. Go through the gateway and continue along the right hedge to reach a stile.

    The hill to your left with the large mast is Caradon Hill.

    Caradon Hill is the 6th highest hill in Cornwall with a 371 metre summit. The name is thought to originate from the Cornish word car for fort. The slopes are dotted with the remains of engine houses and the area was once famous for its copper mines, which were discovered relatively late in Cornwall's mining history. In an account documented in the early 20th Century, the area was described:

    On Saturday nights after pay-day, the populous villages of Caradon Town, Pensilva, Minions and Crows Nest were crowded with men, and resembled in character the mining camps of Colorado and the Far West.
  27. Cross the stile and walk across the field to the gateway opposite.

    Most of the right hedge is hazel.

    During the mesolithic (middle stone age) period, hazelnuts are thought to have been carried as portable food and this is thought to have led to the rapid spread of hazel to new areas seen in archaeological pollen analysis.

  28. Go through the gateway and cross the field to a metal gate opposite.

    The tall trees ahead are ideal perches for wood pigeons.

    There is no biological distinction between "pigeon" and "dove" although "dove" seems to now be used for the more elegant species and "pigeon" for the more unexciting ones. Due to the Norman ruling classes, it's relatively unusual in the English language for the French/Latin word to be the vulgar form and the Norse/Germanic word to be the "posh" form. It's is likely that the reverse was true in mediaeval times: pigeon meat was considered super-posh and the French word was used for the young, tender birds of the species that were eaten.

  29. Go through the gate and follow the waymarked path ahead until it ends on a drive.

    Both navelwort's Latin name and common name are based on its resemblance to a belly button. Other common names include wall pennywort and penny pies due to the shape and size resembling an (old) penny.

  30. Follow the track downhill, passing Penhale farm and a footpath sign on the right. Continue downhill on the track, marked as a Private Road, until it ends in a T-junction on a lane.

    The small stream that is crossed by the track is a tributary of the River Seaton.

    The source of the River Seaton is in Minions near the Cheesewring Hotel and it connects with two tributary streams running through St Cleer. Due to the copper mining activity around Caradon Hill, the tributary streams contain dissolved copper salts where the groundwater drains from old mines or percolates through waste tips. The level of copper in the main river is not high enough to prevent fish living in it but it does restrict the invertebrate species that are able to live in the river and so the fish population is lower than surrounding rivers as there is less for them to eat. The river runs for just over 10 miles before reaching the sea at Seaton beach.

  31. At the junction, St Cleer Holy Well is roughly 30 metres to the right on the opposite side of the road if you want to have a quick look, and the walk continues downhill to the left. Follow the lane downhill and continue until it ends in a T-junction with the main road.

    St Cleer Holy Well, situated on the appropriately-named Well Lane, is a natural spring covered by an elaborately-carved Victorian well house, constructed in 1864. A well house possibly dating back to mediaeval times had stood there previously but it was knocked down during the English Civil War in the 17th Century and lay in ruins until the Victorian reconstruction. The water from the well is reputed to cure madness, but in our scientific trial of one of the iWalk team drinking some and another being the "control", no significant difference in sanity regarding the appeal of walks in the pouring rain was observed. According to one source, the cure is only achieved by immersion in the well, for which there were fewer volunteers. A 9ft tall Latin cross carved from granite stands beside the well.

  32. Carefully cross the road to the bridleway opposite. Follow the track a short distance until you reach a wooden gate on the left, just before a "Homefield" sign.

    The reputation of holy wells to cure madness stems from the mediaeval practice of "bowsenning" the "insane". This consisted of, without any warning, shoving the unfortunate person who was in a state of psychosis (and therefore already highly distressed) into the cold water. In many cases, this only increased the level of distress but the fatigue resulting from trying not to drown was mistaken for improvement. It is also possible that in a few cases that the shock caused a mental reboot which did bring a sufferer out of a mild psychotic episode, and these occasional successes fuelled enthusiasm for the practice. It is also possible that "insanity" was occasionally alcoholically-induced and similar improvement was noticed. For the very unfortunate sufferers that did not recover on first round of "treatment", the practice was repeated regularly.

  33. Bear left through the wooden gate and follow the path between the walls to emerge on a track beside a metal gate. Continue between the hedges until a path leads off to the left just before the track goes through a gate.

    "Holy wells" were created because the Christian church was unhappy with the people continuing their old Pagan ways and worshipping sacred springs. In the 10th Century, the church issued a cannon (law) to outlaw such practices. This didn't work, so they issued another one in the 11th Century, and again in the 12th Century. Even despite the church going to the lengths of building a chapel over the top of some springs to obliterate them, the people still hung onto their sacred springs. The church finally settled on a compromise and rebranded the springs as (Christian) Holy Wells, so the old practices could continue behind a Christian façade.

  34. Bear left onto the path and follow this until it ends in a gate onto a lane.

    Trethevy Quoit, near Tremar, is a 9ft tall 4000 year old Dolmen (burial chamber) with a 10 ton capstone that would have originally been buried in earth. It is one of the two known as "King Arthur's Quoit". The other one is situated at Trethevy near Tintagel, which is pretty confusing, since that one isn't known as "Trethevy Quoit". If that isn't confusing enough, the one near Tremar is sometimes referred to as Trevethy rather than Trethevy. It appears on a 1614 map as "Trethevy Stones".

    More information about Trethevy Quoit from the Cornwall Heritage Trust.

  35. Go through the gate to the lane.

    The walk continues along the lane to the right but first you might want to have a look at Trethevy Quoit which is through the gate on the left.

    Follow the lane for just under half a mile until it ends at a T-junction.

    Dolmens, also known as quoits, are a type of megalithic tomb, usually consisting of three or more upright stones supporting a large flat horizontal capstone. These were usually covered with earth or smaller stones to form a barrow, though in many cases that covering has weathered away, leaving only the stone "skeleton" of the burial mound remaining.

  36. Turn left and follow the road around a bend to the right and up the hill until you reach a crossroads with a signpost to St Cleer.
  37. Turn right onto the lane signposted for St Cleer and follow the lane until it ends at a T-junction.

    The Market Inn, facing St Cleer church, dates from mid-19th century, when St Cleer developed into a sizeable settlement due to the growth in the mining industry on Bodmin Moor. In the 1850s, there were around 4,000 miners working in the South Caradon area.

  38. Cross the road and go through the gate into the churchyard. Follow the path through the churchyard to a gate in the far left corner.

    St Cleer church was first built around AD 800 and subsequently rebuilt in the 13th Century. The tower suffered damage and was rebuilt in the 15th Century; it is just short of 100ft tall and contains 6 bells.

    The church is dedicated to St Clarus, who was born in Rochester in the 9th Century and went to Normandy to become a Benedictine monk. He was, somewhat harshly given his profession, beheaded after rejecting the advances of a noblewoman.

  39. Exit the churchyard and join the pavement on the road ahead. Follow the road to a junction to the left at The Forge.
  40. Turn left past The Forge and then almost immediately right past Primrose Cottage onto Treworrick Lane. Follow the lane through any gates across the lane until the lane eventually ends in a T-junction.

    The tall trees alongside the road provide perches for buzzards.

    In a natural habitat, buzzards perch at the top of trees to survey the surrounding fields. Their brown-and-white pattern camouflages them quite well so it's quite common for walkers to inadvertently disturb what turns out to be a huge flapping monster just feet away. Telegraph poles provide a perfect alternative to trees without any cluttering branches so buzzards can often be seen perched on the top, unfazed by cars passing beneath.

  41. Turn right onto the lane and follow it until it ends in a T-junction at Redgate Smithy.

    The valley that the road climbs from is the beginning of the catchment area for the East Looe River. A small stream runs along the bottom of the valley which is technically the East Looe River. When you reach the main road, you are on the watershed between the Fowey and Looe rivers.

  42. At the junction, carefully cross over the road to the lane almost opposite signposted to Golitha Falls. Follow this back to the bridge to return to the car park.

    When a tree prepares to shed a leaf, it creates a barrier of cells to close the leaf off. Sugars produced from photosynthesis which normally flow back into the plant instead build up in the leaf and react with proteins in sap to form red anthrocyanin compounds. Sunny autumn days produce more sugars and result in more red leaves. Frost causes the leaves to drop off quickly so mild, sunny autumns produce the best red colours.

    Inkies started in 2014, initially catering at events and won the southern heat of the British Street Food awards in 2015. In 2016, Inkies moved to the Golitha Falls car park after acquiring a lease from Cornwall Council and refurbishing the toilets which had been closed for 5 years. Initially the smokehouse was just a converted horsebox in the car park. A crowdfunding project raised money to build the log cabin.

Wagtails are easily recognised from the tail pumping behaviour that their name suggests. Despite being very conspicuous, the function of this curious behaviour is not well understood. It is possibly a signal to predators that the wagtail has seen them, so there's no point trying anything.

Two of the wagtail species are easy to confuse as they are both grey and yellow.

Grey wagtails nest close to fast-running streams as they feed on aquatic invertebrates. They have pink (skin-coloured) legs.

Yellow wagtails are more often found in open fields and have black legs.

The third kind of wagtail more often seen in urban environments - the pied wagtail - is easy to distinguish due to the lack of yellow: it's entirely black-and-white.

Beard-like lichens (known as Old Man's Beard) are very sensitive to sulphur dioxide in the air. Where the air quality is poor, at best they only manage to grow a few millimetres and may not survive at all. Long beards are therefore an indicator of clean air.

Foxgloves have a life cycle which spans two years. The seeds germinate in spring and during their first year they produce a "rosette" of large, velvety green leaves with toothed edges. These are particularly noticeable from October onwards once other vegetation has died back. The leafy foxglove plants remain dormant throughout the winter, ready for a quick start in the spring.

In spring, whilst foxgloves seeds are germinating, the established foxglove plants from the previous year start producing their characteristic flower spike. Once these have been fertilised and the seeds have been produced then the plant dies. One foxglove plant can produce over 2 million seeds.

Foxgloves are reliant on bumblebees for pollination and bumblebees are much more active when the weather is good. Partly, as an insurance policy against bad weather, foxgloves have evolved to stagger their flowering over several weeks, starting with the flowers at the base of the stalk and working up to the top, where the higher flowers protrude over other vegetation that has grown up in that time.

The male and female parts of a foxglove flower mature at different times to help avoid self-fertilisation. This also ties in with the flowers maturing at the bottom of the spike first as pollinators often start at the lowest flower and then work upwards. They land on the mature female flowers first with a cargo of pollen from another plant, and then leave via the mature male flowers with a new load of pollen.

Although nearly all foxgloves are purple, a fairly rare white form does occur and an even more rare pink form sometimes occurs along with this.

As well as attracting insects, the brightly coloured foxglove flowers serve as a warning for animals that the plants contain toxins. All parts of the plant can cause a range of ill-effects in humans from nausea to heart and kidney problems which can be fatal.

The common name "foxglove" dates back many hundreds of years but the origin is unknown. The "gloves" almost certainly refers to the shape of the flowers, and the Latin name Digitalis (finger-like) is along similar lines. The curious part is the "fox" and many different suggestions have been made as to where it came from. It is possible that it is a corruption of another word. One suggestion is "folks" which was once used to mean "fairies".
