Tall elegant spikes create maximum impact at the back of borders year after year. From pure white to violet. Magnificent cut flowers!
Sow indoors for surest results, February-May, 0.5cm (¼”) deep, in a tray of compost. Water well and place on a warm kitchen windowsill. A temperature of 15-20°C (60-68°F) is ideal. Keep moist. Seedlings usually appear in 21-42 days. Transplant individually, when large enough to handle, to 7.5cm (3″) pots (always hold by a leaf, never by the stem). Gradually accustom young plants to outside conditions, before planting out into well-drained soil, June-October, 45cm (18″) apart. Or, sow outdoors in a seed bed, May-July, 0.5cm (¼”) deep, into finely-prepared, well-drained soil, which has already been watered. Keep moist and weed free. Thin seedlings to 5cm (2″) apart, before planting out to flowering position in autumn. Flowers: June-August.
Tip: Remove faded flower spikes to encourage a further show of colour. In exposed locations, plants may require staking.
