About
Sempervivum pittonii, the Pittoni houseleek, is a fleshy, succulent, evergreen houseleek with tight, green rosettes tipped with red. Yellow, starry flowers are borne on stems in summer; individual rosettes die after flowering but are replaced by offsets. A rewarding and distinctive houseleek for a sunny, well-drained rock garden or alpine trough.
