Rock Rose

Cistus
A genus of evergreen shrubs native to the Mediterranean region of Europe and northern Africa, that is part of the Cistaceae family.
The Rock Roses have a long succession of bloom with each individual flower lasting only 1 day.
All species prefer full sun on light, well drained soil including sand. Native to Mediterranean climates, they require moist conditions during winter ( but not cold and wet ) and dry summers. They also grow in the Pacific Northwest but thrive only where they are NOT irrigated during summer ( making them great low maintenance xeriscape plants - non irrigated landscapes also sprout less weeds ). Extremely drought tolerant, they may drop some or even most of their leaves during very dry summers then releaf during autumn. Rock Roses are even reported to be fire resistant and are clay tolerant if planted on a non-irrigated slope. Rock Roses prefer shelter from excessive cold winter winds as well as late spring frosts. Most species are great for seaside plantings.
Tip prune young plants for the first 2 years to encourage dense growth.
The Rock Roses are deer resistant.
Propagation is from cuttings taken from non-flowering shoots during fall and also softwood cuttings taken during summer. They do not enjoy transplanting so install small plants on their permanent site.
Seed can also be sown during spring but is not recommended for cultivars as the offspring will be variable both in flower and growth habit.
Most species do not like root disturbance, especially transplanting so they should be moved while small. Most species also dont like hard pruning. Plants that are not watered and fertilized during summer generally remain more compact.
