Wild Parsnip on a roadside

This biennial plant, a member of the family Apiaceae (the umbellifers), is the progenitor from which cultivated parsnips were derived. In appearance there are slight differences between the wild and cultivated plants, both in the leaves and most notably in the size of the roots, but in fact the roots of Wild Parsnip, although smaller, are also edible.

Habitat

Railway embankments, dry roadside verges and other dry grassy locations are the preferred habitat of this summer-flowering plant, which appears to prefer alkaline soils.
