A genus of dicotyledonous perennial herbaceous plants. They have hard leaves and grow in open areas of stony and infertile soils. Their natural growth and their resemblance to old fashioned single roses is where they get their common name – rockrose.
There are 18 to 20 species of rockrose in the Cistus family. They are all native to the Mediterranean and range from plants less than 1′ tall to ones that can get to several feet.
These are great plants for the cool climate of Western Oregon. For us on the coast they continue to put out sporadic blooms even in winter. The main bloom time is late spring through summer. Flowers may be white, pink, or purplish and some cultivars have a red or brown blotch at the base of each petal. This comes from C. ladanifer, so if you plant has such a splotch, then it is a hybrid.
Name Derivation: Derived from kistos, the Greek name for an evergreen shrub
