Achillea - Summer Berries
Masses of tiny flowers create flat plates of colour that balance on tall stems above the aromatic, feathery foliage. This low maintenance perennial provides an explosion of late summer colour to brighten the backs of herbaceous borders. Easy to grow, even on poor dry soils, Summer Berries is ideal for wildlife gardens where it attracts butterflies and other insects. The vivid range of colours also makes yarrow a spectacular cut or dried flower. Height: 60-75cm. Spread: 60cm.
Sow Achillea seed from February to June or September to October on the surface of a good seed compost, and cover with a light sprinkling of compost of vermiculite. Place in a propagator at a temperature of 15-24C or seal the seed tray inside a polythene bag until after germination, which usually takes 1- 3 weeks. Do not exclude light, as this helps germination. When seedlings are large enough to handle, transplant into 7.5cm pots and grow on in cooler conditions. When Achillea plants are well grown and all risk of frost has passed, gradually acclimatise them to outdoor conditions for 10-15 days before planting outdoors. Plant Yarrow at a distance of 60cm apart in full sun in any well drained soil. Overwinter September sowings in a cold frame and plant out the following spring.
