A rock rose (cistus) is a low shrub grown in hot and dry climates. It tolerates poor soils and needs little water. I see it often in coastal landscapes so it must be salt-tolerant too. They are also used for erosion control and in fire-hazard areas. It is amazing to see such mundane usefulness combined with such ethereal gentle beauty.
Some rock roses have red spots at each petal base, such as this orchid rockrose.
Most rock rose blooms have petals crinkled in the bud and sometimes in the open bloom too.
They have beautiful dense foliage sometimes having a grey tinge.
It is so heart-warming to see a plant so beautiful growing cheerfully in such harsh conditions.
