First year flowering favourite
Dramatic, tall border plant with rich purple flower clusters. Hardy with some protection.
Plant Class: Half Hardy Perennial (HHP), Hardy Perennial (HP).
Habit: Bushy, Tall, Upright.
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.
