Description

''Sibthorpia europaea'' is a small prostrate plant forming mats of thread-like stems which root as they creep across the ground. The mid-green hairy leaves are kidney-shaped and deeply notched. The flowers are tiny and develop singly in the leaf axils. They have relatively long stalks and five pinkish corolla-lobes, and appear from June onwards.

It typically inhabits moist, shady locations such as stream-banks, the sides of ditches, woodland, wet heathland, shady path verges, lawns and old walls and banks with a thin covering of soil. In Ireland it grows at altitudes up to but populations seem to be dwindling as it faces competition from the more aggressive New Zealand willowherb.
