Cistus × purpureus 'Sun Rose'

RHS Plant Profile
purple-flowered rock rose 'Sun Rose'
Shrubs

A compact, bushy, rounded evergreen shrub, producing stems to 1m (39in) high and 1m (39in) across, with narrowly lanced-shaped, green, aromatic foliage, which is resinous and sticky when young . The deep magenta-pink, saucer-shaped flowers, comprised of five overlapping petals that are crinkled like tissue paper, have a dark purple botch at their base and surround a circular central boss of orange stamens and a pale yellow stigma. They are produced in large numbers in early to mid-summer. 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
  • Coastal
  • 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

Diseases

May be susceptible to honey fungus
