Sow February to April at 20-25C (68-77F) on the surface of a good free draining, damp seed compost. Apply a fine sprinkling of vermiculite, 6mm (0.25 inch) deep. Place in a propagator or seal container inside a polythene bag until after germination which usually takes 7-21 days. Do not exclude light at any stage, as this helps germination.

Transplant seedlings, when large enough to handle, into trays or 7.5cm (3 inch) pots. Grow on in cooler conditions for 10-15 days before planting out after all risk of frost, 30cm (12 inches) apart.

Prefers a moist, well drained soil in full sun. Flowers summer.
