Halimium

Halimium (rockrose, false sun-rose, or halimium) is a genus of 12 species of evergreen or semi-evergreen subshrubs in the family Cistaceae, closely related to "Cistus". They are native to Europe, North Africa and Asia Minor, with the centre of diversity in the western Mediterranean region.
The leaves are opposite, simple oval, 1–5 cm long and 0.5–2 cm broad, varying from glossy green to tomentose grey-green. The flowers are 1.5–4 cm diameter, with five petals, white or yellow; in some species the flowers are bicoloured with a dark red or brown basal spot on each petal to act as a nectar guide for pollinating insects.
Cultivation and uses.
Several "Halimium" species, and the numerous hybrids and cultivars derived from them, are widely grown as ornamental plants, popular in rockeries. A broader range of colours is available among the cultivars. 'Susan', with bright yellow flowers and a purple centre, has received the Royal Horticultural Society's Award of Garden Merit.
