Birds-Foot Trefoil, which we called ‘eggs and bacon’ because of the variation in colour from deep yellow to orange, gets its name from the shape of its seed-pods, which also give it its less pleasant common name of Grannie’s Toenails in some areas. Common in grasslands, waste ground, seashores and rocky areas, this low growing plant is a brilliant source of nectar for insects, and a food source for the caterpillars of the beautiful Common Blue butterfly. To Victorians, deeply into the symbolism of flowers it represented revenge. Conditions: very hot, dry spell continues. Temperature: Max 25 Min 10 C.
