You'll love how versatile this perennial is, perfect for beds, rockeries or patios, and it even flowers in its first year when grown as an annual. Each packet contains 40 seeds and comes with easy-to-follow growing and care instructions, so you can enjoy up to 45cm of height and spread in full sun and well-drained soil. How to grow: Sow from February to early June on the surface of a good seed compost just covering the seed with a thin layer of compost or vermiculite. Early sowings can be treated like Half Hardy Annuals and will flower in their first year. Germination takes 14-30 days at 15-18C (60-65F). Don't exclude light, sealing in a polythene bag after sowing is helpful. When large enough to handle, transplant the seedlings to boxes or 7.5cm (3 inch) pots, and grow on in cooler conditions. When well grown, gradually acclimatise to outdoor conditions and plant out in late spring after all risk of frost has passed. Plant 30cm (12 inch) apart in full sun and well-drained soil. To treat as a perennial cut down the stems to ground level in the autumn and cover with a thick mulch of compost. Product Specifications: Position in: full sun. Height: Up to 45cm.
