Cosmos come in a wide range of colours to brighten up your borders from mid-summer to the first frosts of autumn. Their daisy-like flowers will attract bees and other pollinators into your garden.
The Royal Horticultural Society is the UK’s leading gardening charity. We aim to enrich everyone’s life through plants, and make the UK a greener and more beautiful place.
