Helianthemum Ben Fhada The Helianthemum Ben Fhada or Rock Rose is a must-have hardy evergreen shrub for the gravel garden, rockery or sunny border. A low-growing, bushy shrub with bright yellow flowers which appear in early May and last through to July, often enjoying a second flush in late summer after pruning! The silvery grey foliage complements the yellow primrose flowers making this variety of Helianthemum a popular choice when looking to add colour to the garden. Extremely tolerant of poor soils and hot dry conditions. The long flowering period is particularly attractive to pollinating insects. Mix and match with other Helianthemums for added interest and contrast! Height: 20cm (8). Spread: 30cm (12).
