Description

Cosmos 'Seashells Mixed' is a delightful collection with unusual fluted petals in various shades of pink, maroon and white. The abundant blooms appear all season long on 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. 'Seashells Mixed' quickly forms tall clumps, 80 cm to 1 m in height and 40 cm wide. Flowering starts in June and lasts until October (or the first frosts). The flower heads measure about 7 cm across and are made up of a layer of fluted petals arranged around a golden central disc. The flowers display a host of harmonious shades depending on the plant: colours include red, carmine, bright pink, rose, white and burgundy. 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

Two cultivation options are available to you: 1. Sowing under shelter in March-April, followed by transplanting into pots before final planting in your flower beds after the last frost. 2. Direct sowing in May (after the last frost), followed by transplanting at a distance of 30 cm or simply thinning out the excess seedlings. It takes between 80 and 90 days from sowing to flowering. During the summer months, removing faded flowers will promote renewal and prolong the flowering period until autumn.
