A bushy, rounded evergreen shrub, producing stems to 1m (39in) high and across, with narrowly lanced-shaped, green, aromatic foliage. White five-petalled saucer-shaped flowers with a central boss of stamens are produced in large numbers in spring. The plant requires full sun and very well-drained soil in which to grow successfully, particularly overwinter, when rainfall may be higher.

How to grow

Cultivation

Grows well in poor, but well drained soil, in a sheltered site and full sun. The foliage may become chlorotic with age when the shrubs are grown on chalky soil.

Propagation

Propagate by softwood cuttings in spring and by semi-ripe cuttings from midsummer to early autumn

Suggested planting locations and garden types

City and courtyard gardens
Cottage and informal garden
Mediterranean climate plants
Patio and container plants
Flower borders and beds

Pruning

Pruning group 8 or pruning group 9 if necessary; they do not respond well to hard pruning so old leggy plants are best replaced. Pinch back young plants after flowering to encourage a bushy habit

Pests

Generally pest-free
