Cosmos - Purity
Cosmos Purity is everyone's favourite and a garden classic. With its delicate pure white flowers on feathery foliage this variety really is a must for the back of borders with an approximate growing height of 90cm. This flower is very attractive to bees and other pollinators and makes for an ideal choice to add height to the back of a border.
Sow from March to May in trays of moist seed compost and cover with a fine sprinkling of compost or vermiculite. Place in a warm place, and keep at a temperature between 20-25°C. Prick off glasshouse seedlings into trays when large enough to handle, 10cm apart, gradually harden off for planting out in May, 50cm apart. Thin direct sown seedlings to 50cm apart as they grow. Flowers from July to October.
