BIRDSFOOT TREFOIL (Lotus corniculatus)
Eurasia, N Africa
Lotus Corniculatus is a low-growing member of the pea family found throughout Britain. This perennial legume forms a dense mat of vegetation, growing in loam, chalk or sand provided there is good drainage. It likes full sun & does not mind whether conditions are sheltered or exposed…
Birdsfoot Trefoil grows in wildflower meadows, in parks & roadsides, on lawns & fields & as a forage plant for grazing animals. It has many lateral roots & a tap root some 120cm long. It is planted for erosion control.
Buds appear in Birdsfoot Trefoil’s mat of tiny green leaves from late April / early May through to September. The buds open into deep YELLOW pea flowers tinged with red; they change to ORANGE as the flowers fade. Once the blooms have gone over, black seedpods appear in groups of three, each threesome resembling a bird’s foot.
