Cosmos Purity

The essential white flower for the cutting garden — and one of the most effortlessly beautiful annuals you can grow. Cosmos Purity produces an abundance of large, silky, pure white saucer-shaped flowers with sunny yellow centres, held on delicate feathery foliage that moves with every breath of wind.

It grows rapidly to form a shimmering cloud up to 1.2m tall, flowering tirelessly from July through to the first November frosts. In the evening light, the white blooms seem to glow — making it a natural choice for a moon garden or a pale, luminous border.

• Cosmos bipinnatus 'Purity' — Hardy Annual
• Height: 90–120cm | Flowers: July–November
• Approximately 100 seeds per packet
• Excellent for cutting — long vase life
• Sow direct or under cover from April

It looks delicate. It is, in fact, remarkably tough. One of the great workhorses of the summer garden.
