Description

Cosmos 'Cupcakes Mixed' is an original selection with fused petals that form graceful, pleated cup-shaped blooms, often filled with a dainty collarette. Colours range from bright pink to clear white. The abundant blooms appear all season long on semi-tall plants, ideal for cutting! Easy to grow and effortlessly romantic, Cosmos thrive in light soil in a sunny position.

Cosmos bipinnatus is a tender annual plant native to Mexico and the southernmost part of the United States. It belongs to the Asteraceae family alongside Dahlias and daisies, featuring the characteristic inflorescences known as capitulums and very fine, feathery foliage. 'Cupcakes' is an award-winning variety bred by Thompson & Morgan. It quickly forms semi-tall clumps, 80-90 cm in height and 40 cm wide. Flowering starts in July and lasts until October (or the first frosts). The flower heads measure about 10-12 cm across and are made up of a layer of fused, petals in a host of pink and white shades. They are often arranged around a dainty collarette, with the usual golden central disc. Cosmos are a magnet to foraging insects and butterflies, including the monarch butterfly. The finely cut, cloud-like foliage resembles fennel leaves and is delicately scented. Flowers are followed by blackish, spiky seed heads (achenes).

Cosmos is an easy-going, rewarding annual that can single handedly fill a sunny slope, border or flower bed. It is perfect to animate romantic or cottage style gardens. Easy to grow even by beginners, this adorable plant with its feathery green leaves and naive flowers bring light and airiness to heavier blooms such as Dahlias. It combines well with perennial sage, Verbena bonariensis and chrysanthemums until the first frosts. It is particularly useful in new gardens mixed with poppies, love-in-a-mist or cornflowers. Its pretty blooms have a long vase life and are ideal for cutting.

Planting and care

Sow Cosmos seeds from March to May, at a depth of 3mm (0.1 in), in a fine soil and cover the seeds with a very thin pinch of vermiculite. Place the seed tray in a mini-greenhouse at a temperature of 18-25°C or wrap it in a polyethylene 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 (2.8 in). Grow them in cooler conditions until the plants are sufficiently developed to be planted outside. When all risk of frost has passed, gradually acclimate the plants to outdoor conditions for 7 to 10 days.

Plant them in full sun, in a moist, well-drained soil, spaced 45cm (17.7 in) apart. Pinch the tips of the shoots on each stem, during transplantation, to encourage branching and the production of numerous flowers. Cosmos prefer a soil pH between 6 and 8.5, corresponding to the soil of their native habitat, the alkaline regions of Central America. They prefer full sun but tolerate partial shade. These plants are drought-tolerant once established, they are not very prone to diseases, but they can be targeted by aphids. Spontaneous seedlings are common, but not always true to type, without becoming invasive.
