Anacyclus pyrethrum

Anacyclus pyrethrum var. depressus is a small, delicate plant for rock gardens. The white, daisy-like flowers, which close in dull light, appear from early to late summer and are red on the underside, making them particularly pretty in bud. The grey-green leaves, which grow in rosettes, are finely cut and fern-like, forming neat mats which may spread over an area up to 30cm (1 ft) across.

Cultivation

Plant in early autumn or mid spring in well-drained soil in full sun. Remove faded flower stems. The plants dis-like winter wet but may be protected with raised panes of glass.

Propagation: Sow fresh seeds in mid autumn in gritty compost in a greenhouse at a temperature of 7-10°C (45-50°F). Pot up individually in early spring. Plant out in early autumn or mid spring.

Stored seeds, once sown in seed compost in late winter, should be frozen for two nights outdoors before being brought back indoors. The seeds may take up to three years to germinate.

Alternatively, take 7.5cm (3in) long cuttings of non-flowering side shoots in early to mid spring or mid to late summer. Plant out spring cuttings in early autumn, and summer cuttings in mid spring the following year.

Pests and diseases: Aphids may infest foliage, making it sticky and sooty.
