Cistus x hybridus (White Rockrose) - Evergreen mounding shrub 2 to 3 feet tall by 5-6+ feet wide with opposite ovate leaves that are dark grey-green and crinkly. In early to late spring appear the flowers, emerging from red-tinted buds at the tips of the branches opening to 1 1/2 inch wide flowers of a pure white with yellow spots at the petal base and bright yellow stamens. Plant in full sun in most any soil so long as it is well drained. Requires little to no irrigation once established. This plant is among the hardiest of the rockroses. It is listed as tolerating temperatures to 10F. In cold tolerance tests conducted by Oregon State University, Cistus x hybridus showed little or no damage during the trial that ran from 2006 to 2009 where the coldest temperature recorded was 17 F. This plant also is a good choice for gardens near the sea coast and has good deer predation qualities and is generally considered a low fuel volume plant for fire concerns, but this assumes plants are maintained as a low growing groundcover. This plant is often seen as a squared-off plant as wide as tall but if planted with enough room and left alone it can become a large scale groundcover that grows to 2 feet tall by 12 feet wide as it did at Western Hills Nursery in Occidental. Cistus x hybridus is a natural hybrid of C. salviifolius and C. populifolius, that is found in southern Europe. It is also called Cistus x corbariensis, so named for the Corbieres Mountains of southern France but the name C. x hybridus is considered to be the most current and is listed as such by the Royal Horticultural Society (RHS) Source List, the International Plant Names Index (IPNI) and Robert G. Page's National (British) Collection of Cistus and Halimium website. The name Cistus is from the Greek word 'kistos' which was the name originally used to describe the plant in ancient Greece.  This description is based on our research and observations of this plant as it grows in containers at our nursery, in our own garden and in other gardens. We also appreciate receiving feedback of any kind from those who have additional information about this plant, particularly if they disagree with what we have written or have additional cultural tips that would aid others growing Cistus x hybridus .
