Description

Cosmos 'Pink Popsocks' is a variety of Cosmos bipinnatus or bipinnate Cosmos with delightful pink flowers of various shapes. This selection features single or anemone-like inflorescences similar to dahlias and double pompoms. They display various shades of pink-lilac to powdery pink. This charming variety is remarkable in borders, flower beds, and containers. Sow these very easy-to-grow cosmos in light, sunny soil.

Cosmos 'Pink Popsocks' is a cultivar derived from an annual species native to Mexico and the extreme southern United States, Cosmos bipinnatus. This half hardy annual plant, related to Dahlias, belongs to the Asteraceae family: it exhibits a characteristic flower head and particularly fine foliage reminiscent of fennel.

'Pink Popsocks' quickly forms a tuft 60 cm high, 45 cm wide. Flowering begins in July, approximately 85 days after sowing, and lasts until early autumn. The flower heads measure 8 cm in diameter. The flower centre consists of a golden disc. Cosmos flowers attract numerous insects and butterflies, including the Monarch. Left standing at the end of the season, their seeds serve as food for birds. The foliage is finely cut into thread-like segments, barely 0.5 to 1 mm wide, and is slightly and pleasantly scented. After flowering, the plant produces blackish achene fruits, spindle-shaped and bristly. The seeds can self-sow, but the resulting plants may not necessarily resemble their parent.

Capable of filling a sunny bank or bed on its own, Cosmos 'Pink Popsocks' is a carefree and rewarding annual plant, perfect for enhancing a romantic or country-style garden. Cosmos are perfect flowers for beginners, almost impossible to fail with. They grow quickly, adding a lot of lightness to the heavier blooms of Dahlias, and complement perennial salvias, Verbena Bonariensis, and chrysanthemums until the first frosts. Perfect for filling a brand new garden, mixed with poppies, love-in-a-mist, or annual cornflowers. Its flowers hold up very well in a vase.

Planting and care

Sow Cosmos Pink Popsocks seeds from March to May, at a depth of 3mm, in a fine soil and cover the seeds with a very light sprinkling of vermiculite. Place the seed tray in a propagator at a temperature of 18-25°C or wrap it in a polythene bag. Keep the soil moist, but not waterlogged. Light promotes germination, which occurs 7 to 15 days after sowing.

When the seedlings are large enough to handle, transplant them into individual pots with a diameter of 7cm. Grow on in cooler conditions until the plants are sufficiently developed to be planted outside. Once all risk of frost has passed, gradually acclimatise the plants to outdoor conditions over 7 to 10 days. Plant them in full sun, in moist, well-drained soil, spaced 50cm apart. Pinch the tips of the shoots on each stem during transplantation to encourage branching of the stems and the production of numerous flowers.

Cosmos prefer a soil with a pH between 6 and 8.5, corresponding to the soil in their original habitat, the alkaline regions of Central America. They prefer full sun but can tolerate partial shade. These plants are drought-resistant once established, are not very prone to diseases, but can be a target for aphids. Spontaneous seedlings are common but not always true to type, without becoming invasive.
