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 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]
