Bird’s Foot Trefoil

We’ve always associated this plant with sun-baked, very dry, shallow soils in which it happily survives in the wild. But the stress and high temperatures of a green roof test even this plant. Best grown in soils 120mm-180mm deep for it to do well.  In the right place its a great plant, good for bees and of course the food plant for seven native butterflies. Happy days.
