Rose Rock: Cistus
Rockare evergreen shrubs native to the Mediterranean that can grow up to 1.5 m (5 ft) high in the wild. The are borne in cymes at the end of the branches and appear in early summer. C. ladanifer has white flowers and C. x purpureas pink flowers while those of C. laurifolius are also fragrant.
They prefer a sunny, warm position. In summer they need plenty of water but do not tolerate being. Plants should be given weekly applications of fertilizer until the end of the summer. Large specimens can be cut back after flowering but otherwise they do not need any . Seedlings will develop into bushy shrubs in only a few years. Cistus can also be propagated from cuttings taken in summer.
In regions where winters are mild they can remain outdoors in winter. Otherwise they should over-winter in frost-free conditions at a temperature of 5-10° C (41-50° F). Good ventilation is paramount to prevent grey mould. Greenfly and white fly may be a problem.
