Cupcake White Cosmos Seeds – 200 Semi-Double Flower Seeds for Garden

Cupcake White Cosmos is a charming annual flower known for its semi-double, pure white blooms that resemble delicate cupcake liners. These airy, daisy-like flowers rise on slender stems above finely cut, ferny foliage, bringing a light and graceful texture to garden beds and borders.

Easy to grow from seed, this cosmos variety thrives in full sun and tolerates poor to average soil, making it a reliable choice for beginner gardeners and low-maintenance gardens. The plants bloom prolifically from midsummer until frost, providing a long season of white flowers that contrast beautifully with other colorful annuals.

Planting & Care

Sow Cupcake White Cosmos seeds directly outdoors after the last frost date, or start them indoors 4–6 weeks before transplanting. Lightly press seeds into the soil surface and keep moist until germination, which typically occurs in 7–21 days at 70–75°F. Thin seedlings to stand 12–18 inches apart to allow good air circulation. These plants prefer full sun and well-drained soil; avoid over-fertilizing, as rich soil can promote leafy growth at the expense of flowers.

Once established, water moderately and allow the soil to dry slightly between waterings. Deadhead spent blooms regularly to encourage continued flowering and maintain a tidy appearance. Cupcake White Cosmos is generally pest-free and deer-resistant, making it a low-maintenance choice for borders, cutting gardens, and wildflower meadows.
