Cross-leaved Heath

Scientific Name: 
Erica tetralix

Cross-leaved Heath is a type of heather that gets its name from the distinctive whorls of four leaves that occur along its stems. An evergreen shrub, it prefers acid bogs and wet heath or moorland. It flowers between July and September and attracts many nectar-loving insects including bees and moths.

How to identify: 
Cross-leaved Heath has pink, bell-shaped flowers clustered at the end of long, branched stems. Grey-green leaves are narrow and in whorls of four.
Where to find it: 
Widespread: found throughout the UK, but most abundant in the north and west.
How people can help: 

Purple-carpeted heaths are an iconic feature of the UK's landscape and are the result of hundreds of years of low-impact human activities such as livestock-grazing and scrub clearance. Yet development and the decline of traditional farming methods have caused many of these precious habitats to be lost - over 80% of lowland heathland in the UK has disappeared in just 200 years. The Wildlife Trusts manage many heathland habitats for the benefit of wildlife; by volunteering for your local Trust you can help too, and you'll make new friends and learn new skills along the way.

Statistics: 
Height: up to 30cm
Conservation status: 
Common.
Did you know?: 
Cross-leaved Heath, along with other heathers like Ling and Bell Heather, are ideal for wildlife gardens. Plant an ericaceous border (acid-loving plants) and enjoy watching the bees buzz from flower to flower on a lazy sunny afternoon.

Deptford Pink

Scientific Name: 
Dianthus armeria

The Deptford Pink has declined rapidly in range and is now known to inhabit only about 15 sites in the UK, mainly in the south. It prefers light, sandy, acidic soils and requires open conditions to grow well. It can be found on disturbed ground, such as tracks and field edges, along hedgerows and in dry pasture.

How to identify: 
The Deptford Pink has a long flower stalk and deep pink petals that have delicate, pale spots and ragged edges. It has a rosette of green leaves at its base.
Where to find it: 
Very localised and rare, scattered in England, Wales and Ireland.
How people can help: 

The Deptford Pink has suffered serious declines over recent years mainly due to the intensification of agriculture and removal of hedgerows. The Wildlife Trusts are working closely with farmers and landowners to promote wildlife-friendly practices to help this and many other species. We are working towards a 'Living Landscape': a network of habitats and wildlife corridors across town and country, which are good for both wildlife and people. You can support this greener vision for the future by joining your local Wildlife Trust.

Statistics: 
Height: up to 60cm
Conservation status: 
Classified as a Priority Species in the UK Biodiversity Action Plan and as Endangered in Britain on the Red Data List. Protected in the UK under Schedule 8 of the Wildlife and Countryside Act, 1981.
Did you know?: 
The Deptford Pink was named by a 17th century naturalist, Thomas Johnson, who described a pink flower growing in Deptford in East London. Yet it is highly likely that he was actually describing its cousin, Maiden Pink, and that this flower probably hadn't grown in the area since the city of London was built.

Marsh Cinquefoil

Scientific Name: 
Potentilla palustris

Marsh Cinquefoil likes wet, boggy places, fens and peaty meadows. When it is in flower, between May and July, it is a good source of food for nectar-loving insects such as bees and hoverflies. Marsh Cinquefoil is one of a number of cinquefoils, but is unique in the UK as the only one with deep red flowers - the rest have yellow flowers. It is a member of the rose family.

How to identify: 
Marsh Cinquefoil can be identified by its deep red, star-shaped flowers (the red 'petals' are actually sepals) and the pinkish tinge to its green parts. Its leaves are divided into five long lobes with toothed margins.
Where to find it: 
Widespread in the north and west of Britain, less so in the south and East Anglia.
How people can help: 

Human activity, including the drainage of land for agriculture, the loss of ponds through development and the removal of wet woods, has resulted in the disappearance of many of the UK's wetlands. The Wildlife Trusts are working closely with planners, developers and farmers to ensure our wetlands are protected. You can help by becoming a member of your local Trust; you'll find out about exciting wildlife happenings, events on your doorstep and volunteering opportunities, and be helping local wildlife along the way.

Pheasant's-eye

Scientific Name: 
Adonis annua
How to identify: 
The beautiful wine-red flowers of Pheasant's-eye have black, poppy-like centres and delicate, feathered leaf segments.
Where to find it: 
Very rare and scare, most likely found in southern Britain.
How people can help: 

Before the Second World War, arable weeds, such as Pheasant's-eye, would have peppered the landscape with colour in the summer months. But the post-war intensification of agriculture and widespread use of herbicides have driven these species to the brink of extinction in the wild. Nevertheless, The Wildlife Trusts manage many farmland and grassland habitats for the benefit of these plants, often using traditional methods. By volunteering for your local Trust you can help too, and you'll make new friends and learn new skills along the way.

Statistics: 
Height: 10-40cm
Conservation status: 
Classified as a Priority Species in the UK Biodiversity Action Plan and as Endangered in Britain on the Red Data List.
Did you know?: 
The seeds of Pheasant's-eye, like many arable weeds, are able to remain dormant in the soil for a long time, until conditions become suitable again, for example, through the clearing of woodland or disturbance of soil during road construction.

Cornflower

Scientific Name: 
Centaurea cyanus

Once considered as a weed of arable fields, the development of intensive agricultural practices all but wiped out Cornflowers in the wild. This delicate, blue flower is now most likely to occur as a garden escapee, as part of intentional wildflower seeding, or as the result of the disturbance of soil containing old seed banks. Its strongholds remain roadside verges, scrub and wasteland. It flowers from June to August, often alongside other 'arable weeds' (also called 'cornfield flowers') such as Corn Chamomile and Corncockle.

How to identify: 
The bright blue flowers are actually composite heads of small flowers, like all of the daisy family. In the Cornflower, the outer florets are star-like, with denser smaller, more purplish flowers in the middle. Stems and leaves are long and pointy with hairy, blackish buds at the tips.
Where to find it: 
Widespread, but scarce and declining.
How people can help: 

Before the Second World War, arable weeds, such as Cornflower, would have peppered the landscape with colour in the summer months. But the post-war intensification of agriculture and widespread use of herbicides have driven these species to the brink of extinction in the wild.

Conservation status: 
Classified as a Priority Species in the UK Biodiversity Action Plan.
Did you know?: 
One of the best displays of arable weeds in the UK can be seen at a Wildlife Trust nature reserve: College Lake in Buckinghamshire. Every summer, a riot of colour can be enjoyed as flowers such as Cornflower and Common Poppy burst into bloom. Once an old quarry, a cache of topsoil was discovered in the 1980s when the area became a nature reserve, and spread over special plots. Dormant seeds in the soil soon grew to produce a stunning display, which is now lovingly cared for by local conservationists.

Dog-violet

Scientific Name: 
Viola riviniana

If you see a violet in the wild, it is most likely to be the Common Dog-violet; this common and widespread plant lives happily in many different habitats including woodland, grassland, heaths, hedgerows and old pasture. It flowers from April to June but its flowers are not scented, unlike those of its cousin, the Sweet Violet. The latter was used in Ancient Greece as a perfume and Medieval Britain as a deodorant.

How to identify: 
The purple flowers of the Common Dog-violet resemble those of pansies. It has heart-shaped leaves and, unlike some other types of violet, has no scent.
Where to find it: 
Very common, grows almost everywhere in the UK.
How people can help: 

The Wildlife Trusts manage many nature reserves for the benefit of all kinds of wildlife, including many different species of plants. But these precious sites are under threat from development, intensive agricultural practices and climate change. You can help by supporting your local Trust and becoming a member; you'll find out about exciting wildlife happenings, events on your doorstep and volunteering opportunities, and be helping local wildlife along the way.

Statistics: 
Height: up to 12cm

Marsh Violet

Scientific Name: 
Viola palustris

The Marsh Violet is a relative of the well-known pansy and likes damp and acidic places such as wet woodlands, bogs and marshes. For gardeners, it makes a good addition to the edge of a pond or a bog garden.

How to identify: 
Flat, green and heavily veined, the kidney-shaped leaves of the Marsh Violet grow out from the base of the plant. Pale lilac flowers that resemble washed-out pansies hang on tall stalks that sprout from the centre of the plant.
Where to find it: 
Widespread in the north and west, local in the south and east, and very rare in central England.
How people can help: 

Human activity, including the drainage of land for agriculture, the loss of ponds through development and the removal of wet woods, has resulted in the disappearance of many of the UK's wetlands. The Wildlife Trusts are working closely with planners, developers and farmers to ensure our wetlands are protected.

Perforate St John's-wort

Scientific Name: 
Hypericum perforatum

Perforate St John's-wort can be found in open woods, along hedgerows and roadside verges and on waste ground. Its bright yellow flowers appear from June to September and the blood-red juice that exudes from its stems has made it a focus for much myth and ritual. For instance, torchlight processions and gorse-burning were just some of the activities undertaken on Midsummer's Day, a pagan festival soon replaced by the Feast of St John the Baptist, hence the common name of this plant. It's also said that the red juice from its stem represents his bloody murder.

How to identify: 
Perforate St John's-wort can easily be identified as it appears to have many tiny 'holes' in its leaves; these are actually colourless glands that give off a 'foxy' smell. It has bright yellow, star-shaped flowers that are peppered with tiny black dots.
Where to find it: 
Found throughout the UK and Ireland, very widespread in England and Wales.
How people can help: 

The Wildlife Trusts manage many nature reserves for the benefit of all kinds of wildlife, including many different species of plants. But these precious sites are under threat from development, intensive agricultural practices and climate change.

Toadflax-leaved St John's-wort

Scientific Name: 
Hypericum linariifolium

Toadflax-leaved St John's-wort is a fussy plant that has very particular habitat requirements, explaining its rarity and limited range. It needs plenty of space with few other competitive plants nearby, and acidic soils in warm areas. Steep rocky slopes exposed to the sun are a favourite. It is a perennial species and flowers between June and July.

How to identify: 
Toadflax-leaved St John's-wort is one of a number of similar species: look for reddish stems, and long, thin leaves that grow from opposite sides of the stalk. Star-shaped flowers are bright yellow and delicately dotted at the edges with tiny black glands.
Where to find it: 
Very rare and limited to south Devon, the west parts of Wales and the Channel Islands.
How people can help: 

Toadflax-leaved St John's-wort is a rare and declining plant due to the loss of open habitats under scrub, particularly Gorse. The Wildlife Trusts manage many heathland and grassland habitats for the benefit of wildlife - careful grazing with traditional breeds and scrub clearance are just a couple of the ways they ensure a balance of plants and cover in these fragile habitats. By volunteering for your local Trust you can help too, and you'll make new friends and learn new skills along the way.

Statistics: 
Height: up to 65cm
Conservation status: 
Classified as Near Threatened in Britain on the Red Data List.
Did you know?: 
Most of the UK's population of Toadflax-leaved St John's-wort (also known as 'Flax-leaved') can be found on Dartmoor.

Opposite-leaved Golden-Saxifrage

Scientific Name: 
Chrysosplenium oppositifolium

Opposite-leaved Golden Saxifrage is a moisture-loving plant that is found in any habitat near damp or wet places, such as by the side of shady streams and in wet woodlands. It is a creeping perennial that forms mats of golden-green flowers between April and June. The flowers form 'trickles of gold' wherever there is seeping water on a bank or streamside.

How to identify: 
Opposite-leaved Golden Saxifrage truly lives up to its name: look for paired, rounded, green leaves with small, golden flowers set amongst them. The flowers themselves actually lack petals, but are surrounded by their golden sepals and yellowish leaves.
Where to find it: 
Widespread and common through the UK but scarce in central and eastern England.
How people can help: 

Human activity, including the drainage of land for agriculture, the loss of ponds through development and the removal of wet woods, has resulted in the disappearance of many of the UK's wetlands. The Wildlife Trusts are working closely with planners, developers and farmers to ensure our wetlands are protected. You can help by becoming a member of your local Trust; you'll find out about exciting wildlife happenings, events on your doorstep and volunteering opportunities, and be helping local wildlife along the way.

Statistics: 
Height: up to 12cm
Conservation status: 
Common.
Did you know?: 
Opposite-leaved Golden Saxifrage has a close relative called Chrysosplenium alternifolium which means 'Alternate-leaved Golden Saxifrage'. The latter is less common, has rounder leaves on longer stalks, larger flowers and can be distinguished by the leaves being alternate up the stem, rather than opposite each other.
