Welcome to our new page.   TreesWetland plants
The original Flora & Fauna page has now been split up to enable a more dedicated area in the site for both of natures wonders.
We wish to expand this page into an informative and pleasurable site of information, both for the local population and visitors.

PLEASE DO NOT REMOVE ANY PLANTS OR ANIMALS.

Lichen (Usnea subfloridana) or old man's beard
is a fruticose lichen and an indicator of clean
unpolluted air. It is common on trees and
sometimes on rocks, especially frequent in the
hilly districts of the north of Britain. It has many
branches, it is green-grey in colour, it is 3-8cm
long and has a blackish base. The branches are
rounded in cross-section and the colour is the
same on the upper and lower surfaces. Small
rod shaped growths are also common.


Bugle (Ajuga reptans)
A good ground cover plant. Rich powder blue spikes of flowers arise above leaves. Flowers: April - June Requires: Damp shade Height:15cm.                                    


Snowberry (Symphoricarpos albus)
The berries are not very attractive to birds but
are eaten by pheasants in hard winters.
The leaves are food for the caterpillars of Death's-head Hawk-moths.
It is a native of western North America, introduced to Britain in 1817.


Blackthorn (Prunus spinosa) leaves are oval in
shape and quite different from the hawthorn's
lobed leaves. Blackthorn flowers are star-like as
opposed to the rounded petals on hawthorn
blossom. Hawthorn flowers generally appear
when the leaves are already on the tree,
whereas blackthorn flowers appear on bare
branches before the leaves.


Flowering Currant (Ribes sanguineum)
&   Bumble Bee.
Originates from dry open woods and rocky
slopes in western North America as far south as California. It was introduced in to Britain in 1817.


Herb Robert  (Geranium Robertianum)
Herb Robert leaves were crushed to make compresses for bruises and wounds. Can be taken internally for diarrhoea, peptic ulcers and bleeding. External use includes inflamed gums and herpes. Plant was highly regarded by the Scots and was made into an infusion to treat cancer, wounds and skin diseases.


Ladies Smock (Cardamine pratensis)      or
Cuckoo Flower.
It is grown as an
ornamental plant in gardens,
and has as a result of cultivation become

naturalised
in North America.


Lesser Celandine (Ranunculus ficaria) Lesser celandine, also known as fig buttercup, is an herbaceous, perennial plant. Plants have a basal rosette of dark green, shiny, stalked leaves that are kidney- to heart-shaped.


Bluebell (Endymion nonscriptus) Poisonous
The Bluebell is a West-European bulb, which
may bloom (according to local climate and
conditions) from the beginning of April to the
end of May. Not to be confused with the
Scottish 'Harebell', which has 'Bluebell' as a common name too. Found throughout the
British Isles in woods and hedgerows, but rarer
in Northern Scotland and South and Central Ireland. A classic species of old woodland. Also
known as the 'Wild Hyacinth'.


Garlic Mustard (Alliaria petiolata)
Occurrence: Garlic mustard is a native winter
annual, biennial or monocarpic perennial
abundant in damp shaded areas, common in
hedgerows and at the edge of woods. Although
found in hedge bottoms it does not spread far
into arable fields and is largely absent from
agricultural land. It is common on heavy soils
but is most abundant on phosphate rich and
calcareous soils, particularly chalks. Seedling
density can be extremely high. It is considered
invasive because it can quickly become
dominant in understorey vegetation, eliminating other species. Plants exhibit considerable plasticity in different habitats.
Garlic mustard is edible and has been used as
a salad green. It has a characteristic odour of
garlic and if eaten by cows it will taint their milk. It is a food plant of the green-veined white butterfly (Pieris napi) and a site for egg laying.


Ivy Hedra (Genus: Hedera. Species: helix)
Common Name: English ivy.
A single English ivy plant can find many uses all round the garden. It can be used to cover a wall
in shade where few other plants thrive, it can be trained to climb up or spread out along a low
wall. Being evergreen, it is perfect for covering pergola poles, or creating a leafy backdrop
under clematis and climbing roses that provides
winter interest. Or use young plants to train around the outsides of winter hanging baskets. English ivy can be trimmed into shape at any time of year. It is a valuable plant for wildlife and is recommended
by the RSPB, particularly for providing berries for birds in winter when most others have been
eaten. Many insects also feed on the nectar of its white flowers. Be careful when handling it if you have sensitive skin as its sap can be irritating.


Creeping Lady's-tresses (Goodyera repens)
This species has a well-developed system of creeping rhizomes, from which arise rosettes of long-stalked, pointed-oval leaves with a well-marked network of pale veins. Forest clearance can result in the destruction of populations.
The plant flourishes best in years of good
rainfall, and may fail to flower in very dry summers. A plant of coniferous woodland, growing particularly well in the deep leaf-litter and moss under Scots Pine.  It grows as far south as Westmorland and has an outlying population centre in north Norfolk, where it
grows in several sites under planted pine trees.
It is uncertain whether it was introduced there with Pine seedlings or has arisen naturally from airborne seed. It is absent from Ireland,
Orkney, Shetland and the Western Isles.  


Scottish Harebell (Campanula rotundifolia)
When is a bluebell not a bluebell? 
When it is Scottish? When it is a
harebell? The British bluebell and the Scottish 
bluebell are different plants, but both have blue, 
bell-shaped flowers. 
The Scottish bluebell is also called the harebell, 
but generally not in Scotland. Confused?
The same common name can often refer to 
different plants in different places. To avoid
confusion, every species also has a specific, 
international, scientific name. This is like your
first name and surname. Campanula is Latin for 
a small bell (just like campanology means 
bell-ringing) and rotundifolia means round foliage. 
The round-leaved bell-flower, quite simple really.


Hawthorn (Crataegus monogyna)
Fragrant white flowers in May, followed by spherical, glossy, dark red fruit, and deeply lobed, glossy, dark green leaves. Hawthorn makes a great specimen tree or boundary hedge for a range of settings. A valuable food source and refuge for native birds and insects, the spiny thorns serve as a deterrent against potential intruders.
                                      


Daisy (Bellis perennis)
The word 'Daisy' comes from "Day's Eye". The Daisy Family is one of the most successful of all the flowering plant families.



Broad Leaved Dock (Rumex obtusifolius)
Names: Broad-leaved dock
( broadleaf dock, butter dock, cushy-cows, kettle dock, smair dock )
The two main dock species are the broad-leaved dock (Rumex obtusifolius) and the curled dock (R. crispus). Dock seed numbers in soil have been estimated at 5 million per acre. The seeds contain a chemical that inhibits microbial decay and are capable of surviving in undisturbed soil for over 50 years.

Ground-elder (Aegopodium podagraria)
Other names: Bishop's Weed, Goutweed,
Goutwort, Goat-herb, Herb gerard, Garden
plague, Snow-on-the-mountain, Jack-jump-about
Family: Apiaceae.  Perennial, spreading mainly
by creeping underground stems, sometimes by
seed. Although they have been found down to 30 feet or more in cave systems.
ERADICATION: Every last tiny piece of the plant must be removed to avoid infestation. It is a member of the Umbellifer family so can act as an alternate host for the Carrot Fly Grub.
It was introduced from Continental Europe as a pot-herb and a medicine against rheumatism and gout (hence the common name). The leaves can be boiled like spinach (as it still is in Scandinavia), or fresh young ones can be added to a salad - too much has a laxative effect. The dried root can be ground into a flour for baking.

Red Campion (Melandrium Rubrum)
Names: Adders' Flower, Jack-by-the-Hedge, Red Mintchop, Soldiers' Buttons and Scalded Apples. Generally flowers May to September but sometimes goes on longer. Pick Red Campion and your father will die, or so people used to believe. Red campion is a plant of acid or neutral soils, and is wonderful for the herbaceous border, or for naturalising in a hedge-bottom or wooded area of the garden. Red campion is a common spring-flowering plant that in some areas is known as the 'cuckoo-flower' as it shares a season with this winged harbinger of spring. During May, it can often be found in association with bluebells and early purple orchids in the same area. The flowers are, as the common name suggests, red in colour, but pink and white-flowered varieties may arise. The leaves at the base of the plants are elliptical in shape with long winged stalks. The upper leaves are hairy, have short stalks and are more oblong in shape. When the plant has ceased flowering, the seed capsules become apparent; these capsules open at the top, allowing the numerous small black seeds to escape.

Stinging Nettle (Urtica dioica)
(Urtica is from the Latin urere - 'to burn')
Other names: Devil's Leaf, Heg-beg. Tiny stiff hairs on the leaves are hollow enabling them to inject a cocktail including formic acid and histamine which causes a painful rash. An old remedy for the sting is to use Dock leaves or perhaps the more soothing, clear, slimey sap found at the base of the leaf stalk.

Common Rock-Rose
(
Helianthemum nummularium)
The yellow shade of the flowers can vary, with some forms having orange spots at the base of each petal. Has a preference for south to southwest facing slopes and cannot tolerate shade. Can pollinate itself without the need of insects, if necessary. In extreme drought it can shed leaves, and is tolerant to both frost and drought. Has associations with a number of butterfly species including the Green Hairstreak (Callophrys rubi) and Brown Argus (Aricia agestis), which feed on the plant at the caterpillar stage. Rock-rose has protection under the Wildlife and Countryside Act 1981, making it an offence to uproot it without the consent of the landowner. Is reputed to be useful as a herbal remedy to treat severe fear and anxiety.


Comfrey (Symphytum officinale)
Robust perennial herb, growing on stream banks, road verges and waste ground. Formerly cultivated in cottage gardens for its medical properties. Tired feet can be refreshed with comfrey, which is also used to treat rheumatism and 'hens which are doing poorly'. Practitioners of herbal medicine use it to treat a range of illnesses, including gastric and duodenal ulcers, sprains and athlete's foot.
Another plant that is worth looking up for its properties.


Fern (filix-femina)
The lady fern is one of the prettiest of the deciduous hardy ferns, with delicate, lacy, ladder-like foliage which is a good fresh green colour it looks its best in late spring and early summer when the foliage is still young. It associates well in cool shady corners with other hardy ferns, woodlanders, and shade and moisture loving perennials.


Oxeye Daisy
(Chrysanthemum leucanthemum)
The plant generally grows from 1 to 2 feet high. The root is perennial and somewhat creeping; the stems, hard and wiry, furrowed and only very slightly branched. The leaves are small and coarsely toothed; those near the root are somewhat rounder in form than those on the stem, and are on long stalks, those on the stem are oblong and stalkless. 
By the middle of May, the familiar yellow centred white flower-heads commence to bloom, and are at their best till about the close of June, though isolated specimens may be met with throughout the summer, especially where undisturbed by the cutting of the hay, as on railway banks, where the plant flourishes well. Beneath each flower-head is a ring of green sheathing bracts, the involucre. These not only protect and support the bloom, but doubtless prevents insects trying to bite their way to the honey from below. They, as well as the rest of the plant, are permeated with an acrid juice that is obnoxious to insects. It is to be found throughout Europe and Russian Asia. The ancients dedicated it to Artemis, the goddess of women, considering it useful in women's complaints. In Christian days, it was transferred to St. Mary Magdalen and called Maudelyn or Maudlin Daisy after her. Gerard terms it Maudlinwort.


Mullin (Verbascum thapsus)
Other Names: Adam's Flannel, Beggar's Blanket, Candlewick Plant, Common Mullein, Flannel Mullein, Flannel Plant, Hag's Taper, Jupiter's Staff, Molene, Mullein, Velvet Dock, Velvet Plant, Woolly Mullin.
Properties:
Great Mullein has been used as an alternative medicine for centuries, and in many countries throughout the world, the value of Great Mullein as a proven medicinal herb is now backed by scientific evidence. Some valuable constituents contained in Mullein are Coumarin and Hesperidin, they exhibit many healing abilities. Research indicates some of the uses as analgesic, antihistaminic, antiinflammatory, anticancer, antioxidant, antiviral, bacteristat, cardiodepressant, estrogenic, fungicide, hypnotic, sedative and pesticide are valid.

Creeping Buttercup (Ranunculus repens)
Other names: Creeping Meadow Buttercup, Devil’s Guts, Granny Threads, Ram’s Claws, Sitfast, Tether-toad. Perennial spreading by seed and long branching stolons which root at nodes along their length, forming new plants; one plant can spread over a 4m2 area in a year. Grazing animals can suffer from pain and inflammation leading to diarrhoea caused by a toxin in the fresh plant, but it becomes denatured in dry material so is not a problem in fodder. It is thougt to deplete Potassium in the soil, so having a detrimental effect on surrounding plants.


Mint (Mentha crispa)
Mints are mentioned in early medieval plants lists, they were grown in early English gardens, and were brought to Britain in Roman Times. Apicius, in his famous cook book written in the first century, lists mints in many dishes. Charlemagne (742-814) decreed in 812 that many acres of mint, together with other herbs, be grown in his famous gardens of seventy-eight herbs.The genus name Mentha comes from "Minthe", a charming nymph in classic Greek mythology who was much adored by Pluto. This so angered Pluto's wife Prosperine, that she took her revenge by metamorphosing Minthes into the humble, downtrodden mint plant we now call Mentha. Pluto, unable to undo the spell, was able to soften it by giving Minthe a sweet scent which would perfume the air when her leaves were stepped on - the aromatic herb mint. The seventeenth century herbalist, Nicholas Culpeper wrote that the herb stirs up venery, or bodily lust. However, the Roman Pliny, whilst advising scholars to wear a crown of mint to aid concentration, warned lovers that it was contrary to procreation. The Greeks believed the opposite - their soldiers were warned to avoid it for fear that increased love-making would diminish their courage in battle.


Welsh Poppy (Meconopsis cambrica)
(Bluebell on left)
This genus contains some of the most exquisitely beautiful of all flowering plants. Not the easiest of plants to grow, they do best in moderately rich, woodland soil; moist yet with perfect drainage. More often than not a garden escape, the Welsh Poppy is a true native of rocky gullies and stream. Its closest relatives grow in the Himalayas.


Lesser Periwinkle (Vinca minor)
Myrtle, Creeping Myrtle, Periwinkle, or Vinca
(Apocynaceae - Dogbane Family)
Evergreen groundcover has sparse but attractive Spring blossoms (rare for an evergreen groundcover).
Can become invasive beyond its intended boundaries (even into lawn areas) by its trailing and shallowly-rooting stems.

 


Black Knapweed (Centaurea nigra) (Hardheads)
Black Knapweed is a bit like a thistle without the spines. A tallish plant with brush-like, purple flower heads on top of a ball of pale brown and dark brown 'bracts' (small leaf-like appendages).
Found in grassy places everywhere and in flower during the summer and early autumn.


Clover
  (Trifolium repens)
White clover grows in turfgrass, crops, and landscapes. It is also found in a wide range of different field type environments. White clover can tolerate close mowing. It can grow on many different types and pHs of soil, but prefers clay
Besides making an excellent forage crop for livestock, clovers are a valuable survival food: they are high in protein, widespread, and abundant. They are not easy to digest raw, but this can be easily fixed by boiling for 5-10 minutes. Dried flowerheads and seedpods can also be ground up into a nutritious flour and mixed with other foods. Dried flowerheads also can be steeped in hot water for a healthy, tasty tea-like infusion.


Dog Rose (Rosa canina)
The dog rose has one very attractive burst of lightly scented, usually flesh pink flowers (though they can be pinker or whitish) in summer. They are followed by a terrific show of bright red hips, any left hanging on eventually get taken by the birds. The stems are incredibly prickly, which is one very good reason why it's invariably grown in an informal mixed hedge, helping to keep out neighbour's pets and intruders. This species rose used to be grown by commercial breeders to provide the rootstock of ornamental roses.
A source of vitamin C, the dog rose is used in rose hip syrup. This syrup was given to children during World War II to provide a substitute to citrus fruit which was unobtainable.


Snowberry (Symphoricarpos albus)
Common Snowberry (Symphoricarpos albus) is an important winter food source for quail, pheasant and grouse, but is considered poisonous to humans. The berries contain the isoquinoline alkaloid chelidonine, as well as other alkaloids. Ingesting the berries causes mild symptoms of vomiting, dizziness, and slight sedation in children.


Japanese Knotweed (Polygonum cuspidatum)
False Bamboo, Mexican Bamboo
Japanese knotweed is an upright, shrublike, herbaceous perennial that can grow to over 10 feet in height. As with all members of this family, the base of the stem above each joint is surrounded by a membranous sheath. Japanese knotweed spreads quickly to form dense thickets that exclude native vegetation and greatly alter natural ecosystems. It poses a significant threat to riparian areas, where it can survive severe floods and is able to rapidly colonize scoured shores and islands. Once established, populations are extremely persistent.


Field Rose (Rosa arvensis)
Field-rose is a deciduous shrub, up to 2 m in height which spreads by suckering and putting out slender arching stems into woodland and woodland margins. It also grows along hedges on neutral, lime-rich and heavy clay soils.
The long scrambling stems are often purple-tinged and carry slender, only slightly curved, prickles on a base about 5 mm long.
The white, 5-petalled flowers are 3-5 cm across, and appear in clusters of 1-6 and open in June and July. The styles in the centre of the flower are joined together into a slender column, which persists on the small, red hip.
Facts
The hips are a favourite food of birds in winter. The leaflets may be attacked by gall midges, which fold them upwards, so that the paler underside is visible.Caterpillars of the Small Quaker Moth feed on the leaflets.


Tufted Vetch (Vicia cracca)
Tufted Vetch is similar to a pea in growth habit, sending out noose-like tendrils from the tips of its leaves when it contacts another plant and securely fastens itself. An individual plant may reach a length (or height) of 2 m and its tap root may extend up to 1 m. The leaves are 3-8 cm long, pinnate, with 8-12 pairs of leaflets, each leaflet 5-10 mm long. The plant is fast-growing and flowers prolifically, sending out one-sided racemes of cascading pea-flower shaped purple to violet flowers from the leaf axil during its late spring to late summer flowering period. Tufted Vetch is very similar to Hairy Vetch, but is distinguished from the latter by its smooth stem.


Honeysuckle
(Lonicera periclymenum)
Honeysuckles (genus Lonicera; syn. Caprifolium Mill.) are arching shrubs or twining vines in the family Caprifoliaceae, native to the Northern Hemisphere. There are about 180 species of honeysuckle, with by far the greatest diversity in China, where over 100 species occur; by comparison, Europe and North America have only about 20 native species each. Widely known species include Lonicera periclymenum (European Honeysuckle or Woodbine), Lonicera japonica (Japanese Honeysuckle, White Honeysuckle, or Chinese Honeysuckle) and Lonicera sempervirens (Coral Honeysuckle, Trumpet Honeysuckle, or Woodbine Honeysuckle). Hummingbirds are attracted to these plants.


Red Clover
(Trifolium pratense)
Extensively grown for pasturage, hay and green manure, considered excellent forage for livestock and poultry. Compared with alfalfa, red clover has about two-thirds as much digestible protein, slightly more total digestible nutrients, and slightly higher net energy value. The best approximation to vegetable boullion I ever made consisted of red clover and chicory flowers, boiled vigorously with wild onion and chives. Red-clover flowers are reported to possess antispasmodic, estrogenic, and expectorant properties. The solid extract is used in many food products, usually at less than 20 ppm, but in jams and jellies.


Goose Grass (Galium aparine)
Galium aparine is a herbaceous annual plant of the family Rubiaceae. It is native to North America and Eurasia. It has several common names, including Cleavers, Clivers, Goosegrass, Stickywilly, Stickyweed, Catchweed, and Coachweed.
The long stems of this climbing plant sprawl over the ground and other plants, reaching heights of 1-1.5 m, occasionally 2 m. The leaves are simple and borne in whorls of six to eight. Both leaves and stem have fine hairs tipped with tiny hooks, making them cling to clothes and fur much like velcro. When dried and roasted, the fruits of this plant can be used to make a coffee-like drink. The plant can also be made into a tea. The whole plant is considered rich in vitamin C. Its roots produce a red dye, and the tea has been used as an anti-perspirant (by the Chinese), and as a relief for head colds (home remedy), restlessness, and sunburns. As a pulp, it has been used to relieve poisonous bites. 


Meadow Cranesbill
(Geranium pratense)
This well-loved variety of hardy geranium produces violet-blue flowers with attractive white veining. These appear in early to mid-summer, and will sometimes give a second flush if the plants are cut back hard immediately after the original blooms fade. It is quite a tall plant at around 90cm (3ft) high so some staking may be needed during flowering to keep plants looking tidy. However if neatness isn't the highest priority in the border, it loks wonderful when allowed to flop and ramble into other plants, such as pink roses or silver anthemis. The Royal Horticultural Society have given it their prestigious Award of Garden Merit (AGM) whihc is for plants of outstanding excellence.

Grass (Gramineae family)
What is Grass?
Before we get into the peculiar world of lawn care, let's cover some basics. What exactly is grass?
Grass is the common name for the Gramineae family of plants. With more than 9,000 known species, this family is one of the largest on Earth.
Grass is extremely important to most people's lives, whether they know it or not. For one thing, grass is a major food source all over the world. Rice, corn and oats come from grass plants, for example, and most livestock animals feed primarily on grasses. In some parts of the world, people use grass plants in construction (bamboo is a grass, for example), and wherever it grows, grass plays a vital role in curbing erosion. Grass is also used to make sugar, liquor, bread and plastics, among many other things.
Grasses have a very simple structure, and a very simple way of life. You can better grasp what grass needs when you understand how it actually functions in the world.
At the base of the grass plant, roots grow down into the earth. Typically, grass roots are fibrous, or threadlike. They extend into the soil like fingers, collecting nutrients, soaking up water and securing the plant to the ground.
 

Cuckoo Pint Berries (Arum maculatum)

OTHER: Small insects, attracted by smell and trapped by downward pointing hairs in bract above flowers, are released after dark.
     
Fruit toxic to humans
 

Freshwater plants or weeds can be divided into two :

Flowering plants

Divided into three categories by growth area.       

  1. submerged weeds

  2. weeds with floating leaves

  3. emergent weeds

Submerged weeds  The submerged weeds, along with the floating leaf variety, are the true water plants or hydrophytes. Found where there is water as they will die quickly if exposed; commonly rooted in mud - Canadian pondweed (Elodea canadensis) other examples are the free floating (below surface) Hornwort (Ceratophllum).
All these flowering plants are submerged and only rise above water level to flower. 

Floating leaved weeds   Most of these are rooted in the lake or riverbed and have long, pliable stems. There are a number that are also free floating, such as Duckweed (Lemna), Bladderwort (Utricularia) and Water soldier (Stratiotes aloides).

These plants do float freely at the water surface; the bladderwort is one of the interesting plants as it is carnivorous, the leaves having hair like segments on which are born bladder-like traps which catch and digest prey.

The rooted plants in this category include the Broad-leaved pondweed (Potamogeton amphibium), Water crowfoot (Ranunculus aquatillis), Starwort (Callitriche stagnalis) and the Yellow water lily (Nuphar hutea).

Emergent weeds   This type of plant have erect aerial style leaves arising from open water or mud. These plants grow in situations where water level ranges from just below ground level to about half the maximum height of the plant. These are the larger erect type plants like the grasses (reeds). Part of the family of reeds includes the Common reed (Phragmites communis) these often form dense reed-beds around the margins; other plants in this community (similar to broad leaved plants) are the Water plantain (Alisma plantago-aquatica), Arrowhead (Sagittaria sagittfolia) and the Marsh marigold (Caltha pahuustris).

Flowerless plants

Divided into three categories by position in the plant chain.

  1. Algae   There are two types that will interest us from the freshwater point and these are a) the Blue-green and b) the Green algae.
    a) This algae forms either in a gelatinous mass, filaments or as a single cell. They become abundant in nutrient rich waters in late summer, the algae forms a 'scum' or 'water bloom'. Some of them produce poisons that are dangerous to humans and fish.
    b) The green algae is the largest group of the freshwater algae; the main forms are the desmids, which are single celled plants; and the diatoms, single celled like the desmids but have a wall made of silica. Some free float others attach to plants and stones.

  2. Mosses and Liverworts   Several species of moss are found covering stones, particularly in fast flowing streams. They are often the only plants present which provide shelter for many of the stream fauna. (mosses/liverworts)

  3. Ferns & Horsetails   There are only a few aquatic forms of this type of plant life; two of the commonest are the Quilwort (Isoetes lacustris) which grows submerged in nutrient poor lakes of northern Britain and the Water horsetail (Equisetum fluviatile) which is to be found emerging from shallow waters and bogs/ponds.
