New

Description

Compact bushy plants are smothered with mainly double, dazzling white pom-pom flowers. Improved selection of this fabulous first-year-flowering hardy perennial, growing to 30cm (12in) in the first year and 80cm (32in) in the second. Ideal for the front and middle of borders, as ground cover or as low hedging where it will attract bees and other beneficial insects. Also makes a lovely cut or dried flower.

Sowing Instructions

Sow seed on the surface of lightly firmed, moist seed compost in pots or trays. Cover seed with a light sprinkling of compost or vermiculite. Keep at a temperature of between 15-20C (59-68F). After sowing, do not exclude light as this helps germination. Keep the surface of the compost moist but not waterlogged; germination can take 1-3 months. When large enough to handle, transplant seedlings into 7.5cm (3in) pots or trays.

Growing Instructions

Gradually acclimatise to outdoor conditions for a few weeks before planting out after all risk of frost, 30cm (12in) apart. For best results, grow in any ordinary, well-drained soil in full sun. Plants will increase in height after the first year to 80cm (32in).
