A very popular perennial, producing robust plants with masses of wiry stems topped by attractive clouds of eye-catching, rosy lavender blooms. Ideal interplanted amongst other perennials, adding height and a tranquil feel to borders.

Sowing Info

Sow seed onto the surface of a good, free-draining, damp seed compost. Apply a very fine sprinkling of dry vermiculite. Place in a propagator or seal container in a polythene bag at a temperature of 24-27°C (75-80°F) until after germination which takes 14-21 days. Do not exclude light as this helps germination. Keep compost on the dry side then water lightly as seedlings emerge.

Growing Info

Transplant, when large enough to handle into 7.5cm (3in) pots. Gradually acclimatise plants to cooler conditions for a few weeks before planting out after all risk of frost, 45-60cm (18-24in) apart.
