An unusual perennial for the warm sunny border with sword like rich green leaves and clusters of delightfully speckled flowers, for the first time offered in a wide range of colours. In autumn the seed pods burst to reveal clusters of black seeds like blackberries. Will flower in its first summer from a late winter sowing. Flowers early summer. Height 90-100cm (36-40in).
Sow in late winter/early spring in a good seed compost just covering the seed with compost and gently firm down. Keep soil damp but not wet. Sealing in a polythene bag after sowing is helpful. Germination usually takes 14-60 days at 20-30C (68-86F).
When seedlings are large enough to handle, transplant into 8cm (3in) pots and grow on in cooler conditions. Gradually acclimatise to outdoor conditions for 10-15 days before planting out after all risk of frost, 30cm (12in) apart in a sunny sheltered spot on light well drained soil.
In cold areas protect the roots with a thick mulch of leaves, bracken etc.
