Pure, Cloud-Like Elegance

Cosmos bipinnatus 'Double White' is the epitome of garden elegance. Each bloom is a full, fluffy rosette of pure white petals — layered and ruffled like a tiny peony — held aloft on long, slender stems above a cloud of feathery green foliage. There is something truly magical about a mass planting of Double White cosmos swaying gently in a summer breeze, and as a cut flower it is simply unmatched — clean, classic, and breathtakingly beautiful. Whether you’re growing for the garden or the vase, this is a variety you’ll return to year after year.

Why Gardeners Love It

  • ✨ Fully double pure white blooms — lush, layered petals with a peony-like quality that is rare in cosmos

  • 🌿 Feathery fine-cut foliage — light and airy, adding movement and texture to borders and bouquets
  • 🐝 Excellent for bees and butterflies — a magnet for pollinators throughout summer and autumn
  • 🌱 Easy to grow from seed — fast-growing, free-flowering, and self-seeds gently in the right conditions

Growing Tips for New Zealand

Sow indoors 4–6 weeks before the last frost, or direct sow in spring once soil has warmed. Sow seeds on the surface of moist seed-raising mix and cover lightly. Transplant seedlings to 30–45 cm apart in a sunny, open position with well-drained soil. Cosmos thrives in poor to average soils — avoid overfeeding which encourages lush foliage at the expense of flowers. Deadhead regularly to extend flowering from summer right through to autumn. Performs beautifully throughout NZ in any warm, sunny position.
