Orchid rockrose (Cistus × purpureus, Cistaceae) is a broadleaf evergreen shrub of pre-1790 hybrid origin, reaching 2 to 4 feet tall with a rounded form. Oblong-lanceolate leaves (3 to 5 centimeters) are dull gray-green above and pubescent below. Pink flowers (6 to 8 centimeters wide) with dark red blotches at the petal base and bright yellow stamens appear in clusters of three, each with five petals.
Orchid rockrose grows in full sun on well-drained soil, sheltered from cold and dry wind, and tolerates coastal breezes and salt spray, hardy in Zones 7 to 8. Documented diseases include bacterial brown spot, botrytis blight, leaf spot, virus diseases, and root rot. Root weevil is the primary pest. No cultivars are documented.
