Fabaceae: a clump-forming perennial clover to 80cm. Found on chalky boulder-clays or, more rarely, chalk, in pastures and on road verges, trackways and wood-borders. The flowers are pale yellow flowers, in globular or oblong inflorescence, 2-4 cm, blooming from June-July. The leaves are oblong-elliptical or lanceolate 1.5-3cm. Native to much of Europe. In Britain it is now rare, mainly eastern England.
It is often mentioned in the literature as being particularly attractive to foraging bees and butterflies and when we have grown it as a crop it is certainly visited by a large number of bumble bees particularly Bombus lapidaries and Bombus hypnorum.
Seeds can be sown at any time of the year, may be a little slow to germinate with some evidence that peak germination occurs in autumn.
