Wood Anemones are indicators of ancient woodlands, where they are among the most abundant and attractive of spring wildflowers. Identification Anemone nemorosa is a perennial and grows to a height of about 15cm. The leaves, which die back once the plants have flowered and set seeds, are palmately lobed - very much like the leaves of the majority of other members of the Buttercup family, Ranunculaceae.
The size of the flower heads is very variable; on the edge of the wood they can be twice the average size of 2cm diameter when fully open. Often opening pinkish-mauve colour and gradually turnbrilliant white, the flowers each have six or seven tepals (petals and sepals), but exceptionally they can have up to ten. These flowers,stand out particularly well in springtime, because the main leaves do not appear until after blooming is completed. Wood anemones propagate mainly by means of creeping underground rhizomes. Distribution Common and widespread in Britain and Ireland, Wood Anemones are found also throughout most of mainland Europe except for the very dry and sandy southern parts of the Mediterranean region. This gregarious wildflower has also been introduced to many other regions of the world, including North America.
Habitat These star-like wildflowers line rural hedgerows and carpet the floors of deciduous forests and woods. Blooming Times Wood Anemone blooms from March to May Pollination Wood Anemones are pollinated by a wide range of insects, but research in Germany has shown hoverflies to be particularly important pollinators of this species.
Uses Although it has largely fallen out of popular use, in the past Anemone nemorosa was used by herbalists in remedies for a range of ailments from mere headaches through to leprosy!

So waxy and beautifully veined, these delightful little flowers are quite unlike most other members of the Primrose family. Identification Once you get to see it at close quarters, this wildflower is quite unmistakable. Flowers are 6 to 10mm across with usually 5 to 7 lilac-pink round petals patterned with longitudinal red veins; they are backed by pointed short sepals. The centres contain a tangled mass of filamentous stamens.
Along the prostrate red-tinged stems are opposite pairs of leaves on shortish stalks; most leaves are roundish but some are shaped like the Ace of Spades. A single flower grows on a short up-turned slender stalk at the end of each creeping stem, but when in full bloom the flowers of Bog Pimpernel all but obliterate the leaves, so densely are they packed together.. Distribution In Britain and Ireland this lovely little wildflower is localised in the south and west; it is also found in Ireland where it is also most common on the western side. Bog Pimpernel is found throughout most of Europe except in the far north and in arid parts of the south. Its range extends eastwards into Asia, but this wildflower is not native to North America.
Habitat Anagallis tenella generally favours damp and acidic peaty substrates, but it can also be found in alkaline coastal dune slacks. As with all marsh and wetland plants, the enemy of Bog Pimpernel is land drainage. Blooming Times In Britain and Ireland Bog Pimpernel produces dense mats of flowers that open fully on sunny days from May right through to September.
Uses Don't even think of picking these flowers; they are extremely fragile and likely to break as soon as they are touched. Cultivated forms of Bog Pimpernel are available from specialist garden centres and nurseries, and they make wonderful additions to any bog garden or to the waterlogged margin of a small pond.

Many people are very surprised to learn that Scarlet Pimpernel is a member of the Primrose family (Primulaceae) - as indeed are also the Yellow Pimpernel Lysimachia nemorum and its close relative CreepingJenny Lysimachia nummularia.
Identification This low-growing annual wildflower has square stems, and its oval pointed leaves are black-dotted underneath. The flowers of Scarlet Pimpernel, which are rarely more than 10 to 12mm across and have five sepals (commonly referred to as the petals), open in mid morning, but they close again long before the sun begins to set.
Occasionally you may come across blue-petalled variants of this lovely little wildflower; once in a while we encounter both colour forms growing together (but the two flower colours are always on separate plants). In June 2014 during a visit to Slovenia we came across plenty of Scarlet Pimpernel (brick red form) lining the verges of a main road, and among these prolific conventional plants were numerous with pale mauve flowers. These were not fading red or blue flowers, as several were seen at the bud stage as well as many more in their prime. Other colour forms although seen rather infrequently include maroon, flesh pink, and lilac.
Distribution Scarlet Pimpernel occurs throughout Britain and Ireland and is a very common wildflower - often referred to as a 'weed of cultivation' because it appears most often in farmed fields and gardens and on disturbed wasteland. Even some World War II bomb sites became colonised by this plant. Habitat Well drained, sandy places are the favoured habitat of this lovely little flower, which thrives in cultivated soil. We have also seen Scarlet Pimpernel growing in sandy meadows beside spate rivers in Wales. Blooming Times In Britain and Ireland Scarlet Pimpernel can be found in flower from May right through to the end of October, but it is usually at its best in June, July and August. Uses In old Herbals dating back to the 16th century, Scarlet Pimpernel was used for many dubious purposes both cosmetic (as a skin cream) and medicinal, including to produce potions for countering the effects of being bitten by mad dogs.
