Kniphofia, 'Royal Castle Hybrids'

Germination

Sow indoors Feb-Jun or Sep-Oct. Surface sow onto moist, well-drained seed compost. Just cover with a light sprinkling of soil. Light is needed for germination. Keep moist. Ideal temp. 15-20°C. Germination takes 14-45 days. Transplant seedlings when large enough to handle to 8cm pots and grow on. Ideally grow on in a greenhouse for the first winter. Acclimatise and plant out the following spring.

Growing

Prefers a sandy soil which has been enriched with humus, but any deep, moist but well-drained soil will suffice. Full sun is preferred but will tolerate partial shade with reduced flowering.

Cultivation

Propagate by division of established clumps in late spring. Propagate by taking offshoots from the crown. Old flower stems can be cut down after flowering.
