The Sedums are a large group of fleshy-leaved plants which thrive in hot and dry conditions – their ability to cover rocks and walls is responsible for the common name. Many are rock garden plants but some Sedums, known as Ice Plants, are grown in the herbaceous border. The flower-heads of the Ice Plants are large plates of tiny, their appearance in late summer acting as a magnet for the butterflies in the neighbourhood. These Border Sedums are tough plants, shrugging off drought and pests which would cripple more delicate perennials.
