Cephalaria gigantea (Dipsacaceae)
Stately and striking back-of-border focus
Something rather different from seed for the back of a perennial (herbaceous) border. The large, pincushion-like, yellow flowers of Cephalaria gigantea are borne on long, wiry stems above bushy clumps of dark green leaves. The blooms are a fine nectar source for both butterflies and bees.
Despite the great height of the plant, it almost never needs staking. It is also a good choice for naturalising in ‘wild’ gardens.
Cephalaria is a trouble-free hardy perennial which flowers for the first time in the year after sowing and in subsequent summers. It does well in a wide range of moderately fertile. moisture-retentive soils, including clays which may be liable to compaction. A position in full sun will give the best results.

Sow thinly, indoors, January-March, in pots or trays of compost, just covering the seed. Keep moist and warm. A temperature of approx. 15-21ºC (60-70ºF) is ideal. Germination may be slow. After 3-4 weeks, further germination may be encouraged by placing the pots or trays in a refrigerator for 2-4 weeks, before returning to a gentle warmth. Thin (prick out) to further pots or trays when seedlings are large enough to handle. Gradually harden off in late May, before planting out to flowering position, spacing 75cm (30”) apart. Flowers: June-August.
