cosmos 'purity white' seeds


We can all imagine that picturesque English country garden and it's always bright and sunny, and normally with some of these wonderfully white blooms sitting on apple-green leaves. It's reason enough to be proud to be British, without even mentioning Harry Potter or David Beckham's right foot. Grows to a healthy 110cm, enjoy these in the garden or cut for the kitchen table vase.

about cosmos ‘purity’

Cosmos are prolific flowering annual plants that are easy to grow simply by sowing seeds in the garden after any danger of frost has passed. They will reach full maturity within two months. The flowers sit atop long slender stems and form a cloud of color that not only looks attractive throughout the summer but also attracts bees and butterflies and birds to your garden

in the records

Spanish priests cultivated Cosmos plants in their mission gardens and were so taken with the evenly placed petals they named the flower ‘Cosmos’ the Greek word for ‘ordered universe of harmony’.
