Grow in a well-drained, moderately-fertile soil in full sun. Pinch out the growing tip when the plants are 15-20cm tall to encourage free-flowering, bushy plants. See chrysanthemum cultivation for further information
Propagate by basal softwood cuttings from overwintered stools in late winter or early spring. Cuttings should be rooted in a loamless 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
Pinch out growing tips for bushier plants. Once flowering is over in late autumn, cut the whole plant down to 20cm (8in) tall. It can be left in the ground in free-draining soil and mulched. Alternatively, in cooler climates, lift and store in pots in a cool, dark, frost-free location over winter
