Brachyscome multifida 'Blue Haze'
  • RHS Plants for pollinators

rock daisy 'Blue Haze'

This half-hardy perennial daisy is often grown as an annual, and has a mounding or gently spreading growth habit. It can be used as a bedding or conservatory plant in summer bedding schemes, patio and balcony displays, in containers, window boxes and hanging baskets, but also as a low-growing plant for a sunny rock garden or to spill over a sunny wall. A dainty yet tough cut-leaved 'rock daisy' that can thrive in dry, rocky or shallow soils once well established. It produces pretty pale powder blue daisy flowers with yellow centres that turn golden to bronze brown as they age. Blooms profusely in summer and well into autumn and sometimes winter in sheltered spots if carefully dead-headed. The plant has attractive, fine, deeply-divided mid-green foliage.

How to grow

Cultivation

Grow on in warm frost free conditions. Acclimatise plants before planting outside in early summer. Pinch out growing points while the plants are small to encourage branching and more stems. Regular pinching will create a well balanced compact plant that is perfect for container cultivation. Will grow in any well drained soil in sun.

Propagation

Propagate by softwood cuttings
