Cosmos 'Purity' Seeds
The essential white flower for the cutting garden. 'Purity' is the classic, best-loved white Cosmos, producing an abundance of large, silky, pure white, single flowers with sunny yellow centres. Set against delicate, feathery foliage, these airy blooms dance on tall stems and are a 'cut-and-come-again' staple, providing endless flowers for bouquets.
