This half-hardy daisy 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 dainty plant for a sunny rock garden. A pretty yet quite tough cut-leaved 'rock daisy' that can thrive in dry, rocky or shallow soils once well established. It produces pretty pale to mid mauve-blue daisy flowers with yellow-green to yellow-gold centres. Blooms profusely in summer and well into autumn if 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
