About

A rare and unusual, drought-tolerant, perennial, hardy alpine species with unusual flowers that are pale white to creamy yellow with purple-brown veining. The plant is gently spreading and almost cushion or Sedum-like in appearance. The leaves of the plant are tiny, quite succulent and mid-green in colour. It can reach a height of approximately 8cm and a spread of 30cm. It must have very free draining, quite poor soil in crevices / walls, between rocks in a scree garden or bed, or grow in pots and troughs. Its unique flowers fade to give two different colour combinations of flowers on the same plant.
