Cistus, commonly known as rockrose, is a genus of flowering plants in the family Cistaceae. These evergreen shrubs are native to the Mediterranean region and are well-known for their resilience and ability to thrive in poor, rocky soils. Cistus plants typically have grey-green leaves that are often covered with a sticky, aromatic resin. The flowers of Cistus are large, showy, and resemble single roses, usually with five petals that can be white, pink, or purple. They bloom in late spring to early summer and are often short-lived, with each flower lasting only a day. However, the plants produce a profusion of blooms, creating a stunning display over several weeks. Cistus is also valued for its medicinal properties and its use in the perfume industry, particularly for its fragrant resin known as labdanum. These plants are drought-tolerant and are often used in xeriscaping and coastal gardens.
