Description

Dramatic, tall border plant with rich purple flower clusters. Hardy with some protection.

Sow indoors, January-April, to flower the same year, 0.5cm (¼”) deep, in trays of compost. Water well and place in a greenhouse or on a warm, kitchen windowsill. A temperature of 20-25°C (68-77°F) is ideal. Keep moist. Seedlings usually appear in 21-35 days. If germination is slow or erratic, place the tray in a refrigerator or outside for 1-2 weeks, then return to the warmth. Transplant seedlings to 7.5cm (3″) pots of compost, when large enough to handle. Always hold by a leaf, never by the stem. Gradually accustom young plants to outside conditions (avoid frosts), before planting out into well-drained soil, May-June, 45cm (18″) apart, when frosts are over. Flowers: July to October.

*Plants are hardy to approx. -5°C (23°F). Plants need a sheltered location and protection, with a mulch of straw or peat, is beneficial in winter.
