Gum Cistus

Native to S Europe and N Africa, this genus contains about 20 species of evergreen and semi-evergreen shrubs. Cistuses are attractive plants, popular in dry, warm borders and coastal gardens for their short-lived, but showy flowers. The name Cistus comes from the Greek kiste, "box", and refers to the shape of the capsules. Ladanum. or labdanum, is an oleo-resin made from several species of Cistus, including C. albiflorus, C. creticus, C. ladanifer, and C. maculatus. It is the best plant substitute for ambergris from sperm whales and is important in perfume manufacture. The sticky substance is traditionally collected by whipping the bushes, so that the exude adheres to the leather thongs, or, in Crete, by combing it from the hides of sheep and goats with a leather rake, or ladanisterion. Ladanum is now produced in France and Spain.

Evergreen shrub with a stiff, upright habit and sticky, aromatic, linear-lanceolate leaves, 10cm (4in) long. Solitary, 5-petaled, white flowers, about 7cm (3in) across, with a maroon basal blotch on each petal, appear from early to late summer.
