A superb border plant with silver- green lanceolate foliage and many spikes of claret-red, almost black florets - a highly unusual colour in perennials. May also be used in containers or as a cut flower.
Sow in trays, pots, etc of good seed compost in a propagator or warm place to maintain an optimum temperature of 65-85F (20 – 30C). Surface sow using peat/sand mix seed compost. Sow February to July. Germination usually takes 1-4 months.
Transplant seedlings when large enough to handle into 7.5cm (3in) pots. Acclimatise young plants to outdoor conditions before planting out 45cm (18in) apart in full sun or part shade.
Prefers a moist, well drained soil.
