Cosmos bipinnatus 'Sea Shells Mix' Seeds

Fluted Petals Like Tiny Seashells

Cosmos bipinnatus 'Sea Shells Mix' is one of the most distinctive and enchanting cosmos varieties you can grow. Unlike standard cosmos, each petal is uniquely rolled and fluted into a delicate tube — like a tiny seashell — giving the blooms an extraordinary, almost sculptural quality. The mix includes a beautiful range of colours from soft white and blush pink through to rose, crimson, and lilac, all held on long, elegant stems above a cloud of feathery fine-cut foliage. Whether swaying in a summer breeze or arranged in a vase, Sea Shells cosmos is guaranteed to stop people in their tracks.

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.
