Cistus albidus

The Cotton Cistus (Cistus albidus), also known as the White Cistus or Pale Cistus, is a shrub characteristic of the garrigue; it withstands periods of drought well and thrives in limestone soils.

Name

The plant is known in English as "rockrose" or "white dart."

Etymology

The name "cistus " comes from the ancient Greek word *kisthos*, meaning "box" or "capsule," a reference to the shape of its capsule-like fruit.

The Latin specific epithet *albidus*, meaning “whitish,” refers to the plant’s characteristic downy leaves, not to its pink flowers. It is sometimes called the whitish rockrose or white rockrose.

Features

Cistus albidus is a medium-sized shrub (between 0.5 and 1.2 m tall) in the Cistaceae family.

Its light gray evergreen foliage consists of simple, sessile, opposite, oblong-elliptical leaves covered with star-shaped hairs.

It blooms from April to June, producing a single-branched, spiral corymb inflorescence composed of pink flowers with five crinkled petals. The flowers attract bees, butterflies, and other insects, ensuring entomophilous pollination.

The fruits of Cistus albidus are dehiscent capsules with five valves. The fruits are dispersed by animals.

Range

According to POWO, the natural range of this species is the western Mediterranean region, specifically Algeria, the Balearic Islands, Corsica, France, Italy, Morocco, Portugal, Sardinia, and Spain.

In mainland France, the white rockrose is found mainly in the Mediterranean region.
