Helianthemum apenninum, the white rock-rose, is a white-flowering rock rose of the family Cistaceae found in the North Atlantic region, mainly in dry grassy and rocky places across large parts of Europe. [1] [2] [3]

Helianthemum apenninum, is a self supporting, semi-woody shrub that may grow up to 0.5 meters high and roots unto 0.3 meters deep. It follows a perennial life cycle. [2]

It flowers from March to July and produces pentamerous flowers, white with yellow centers and yellow stamens and up to 30 mm across. The three outer sepals are hairy and striped; the 2 inner sepals are very small. The flowers grow in clusters of 3 to 10 on a stem. [4] The flowers are visited by Marsh Marygold Moth (Micropterix calthella). [2]

It produces Dry fruits with seeds (average 0.9 mg) that are dispersed through autochory (un-assisted or gravity-assisted dispersion). [2]

It is photoautotroph and an Evergreen Plant (maintains foliage throughout the year). The leaves are small (around 30 mm), linear/lance-shaped, in opposite pairs. They are covered with greyish or whitish hairs, especially on the underside, and the edges are rolled under. [4]

Cistaceae Family of flowering plants comprising rock roses

The Cistaceae are a small family of plants known for their beautiful shrubs, which are profusely covered by flowers at the time of blossom. This family consists of about 170(-200) species in nine genera that are not very distinct, distributed primarily in the temperate areas of Europe and the Mediterranean basin, but also found in North America; a limited number of species are found in South America. Most Cistaceae are subshrubs and low shrubs, and some are herbaceous. They prefer dry and sunny habitats. Cistaceae grow well on poor soils, and many of them are cultivated in gardens.
