An erect, woody-based, deciduous perennial, producing stems to 90cm (3ft) high and a spread of 50cm (20in), with deeply divided, aromatic green leaves. In late summer and autumn, the plants produce sprays of single light peach coloured daisy flowers each with a yellow eye. They are long lasting in water and are ideal to grow for cutting. The plants are winter hardy throughout most of the UK, but if grown in colder areas, are best heavily mulched over winter, or lifted after flowering and kept in cold, but frost-free conditions until spring. The flowers are very attractive to pollinating insects and the plant is an ideal choice to include in a wildlife garden

Horticultural Classification Codes

Horticultural Classification Codes are often given to genera which have a large number of species or cultivars. They are used to categorise cultivated plants based on specific, shared characteristics such as shape, colour, size or flowering time, and can be displayed as letters or numbers

For example:
Dahlia ‘Sunset Kate (Sin) = Single flower
Rosa ‘Marigold’ (HT) = Hybrid Tea: Single Korean chrysanthemums are perennials with lobed leaves and single flowerheads

How to Grow

Cultivation

Grow in a well-drained, fertile, moisture-retentive soil in full sun. In cool regions, lift the plants in autumn, before the first frosts and store the crowns in trays of just moist compost in frost-free conditions until spring. In areas where temperatures fall no lower than -5˚C (23˚F) in winter, plants may be left in the ground and protected by a thick mulch over winter, carefully removing this in spring, after the risk of frosts has passed.

Propagation

Propagate by basal softwood cuttings from overwintered stools in late winter or early spring. Cuttings should be rooted in a peat-free compost the surface of which is covered with dry sand and kept in a temperature of 16°C. Place in a cold frame after first rooting and protect from frost. Harden off in mid spring. Established clumps may be propagated by division in spring.
