Flora and fauna: Why wage war against such a cheerful, golden star-like flower?
Lesser Celandine Ficaria verna, (formerly Ranunculus ficaria)
OFTEN the first truly wild plant to flower in our damp woods, banks and gardens, the lesser celandine carpets the ground closely and delights us with bright yellow star-like flowers for several weeks. Indeed one of its folk names is Golden Stars.
Above rosettes of glossy green, heart-shaped and stalked leaves are the single, long stalked bright flowers about 2cm in diameter with usually seven or eight narrow petals and many yellow stamens.
Beneath the petals is a ring of three green smaller sepals, formerly the bud scales. After flowering and fertilisation, a cluster of small fruits called achenes matures in the centre of the flower.
However, celandines also have creeping and rooting stems and produce a cluster of underground tubers containing food stores.
A subspecies produces few if any ripe achenes but small bulbils in the leaf axils which fall off and root when the main plant decays.
This is how they can carpet the ground so quickly and closely. Some gardeners wage an endless war against this carpet but personally I love the cheerful golden flowers.
The nice thing is that after just a few weeks all traces of the carpet will have withered away allowing all the later plants to come through.
Not surprisingly the lesser celandine is a member of the buttercup family but is no relation at all to the greater celandine, a member of the poppy family.
The only thing they have in common is the colour of their flowers.
