Callistephus chinensis 'Blue Ribbon' / China Aster / Seeds

A compact China Aster, with plenty of violet blue cushion shaped flowers throughout the summer.  Flowers come out in July and last right up to the first frost. These are great bedding plants, growing to a height of 20-25cm, and also good to fill the front of a border with late colour.

Callistephus likes full sun and a rich well drained soil. Regular feeding and water will increase the flowering.

Pack of 50 seeds.  Sow in the autumn/winter for an early start, protecting the seedlings over winter in a coldframe or greenhouse, or sow in spring. Sowing instructions and a colour photo are printed on the packet.
