Description
Cosmos bipinnatus Lucinda is a stately annual plant developed for bedding displays and cut flower arrangements. Its large, rounded pure white flowers, borne on long sturdy stems, possess a beautiful natural elegance. They are perfect for bringing a light and luminous touch to the garden throughout the summer.
Cosmos Lucinda germinates in spring, flowers in summer and then dies in autumn. This plant develops slender stems 1 m to 1.20 m in height. Its light green, finely cut and airy foliage showcases the abundance of summer flowers. The large, rounded, cup-shaped flowers measure 6 to 8 cm in diameter. They bloom from July to September in the case of a spring sowing. In mild climates or with an early sowing under cover, flowering can begin from late June and continue until October, especially if the weather remains mild. Regularly removing spent flowers encourages repeat flowering. Cosmos are loved by bees and other pollinators.
The bipinnate Cosmos 'Lucinda' combines harmoniously with other tall Cosmos varieties like 'Rubenza' or 'Sensation Pinkie'. Also pair it with tall cottage garden plants like Echinops bannaticus Blue Glow, Coneflowers, or ornamental grasses like Fountain Grasses. Sow your cosmos in a large seasonal border, a tall herbaceous border, or a flowering meadow.
The eco-friendly gesture: sowing a nectar-rich plant like Cosmos ‘Lucinda’ invites bees and other pollinators all summer long. At the end of the season, leave a few flowers to go to seed: they will feed the birds and promote the biodiversity of your garden.

Planting and care
For Cosmos 'Lucinda', you have two sowing options:
Sow under cover in March-April followed by transplanting into pots before final placement in your borders after the frosts.
Direct sowing in situ in May (after the last frosts) followed by transplanting at a distance of 30 cm or simply thinning out excess seedlings. Allow between 80 and 90 days between sowing and flowering.
Germination takes 7 to 10 days at 15–20°C.
Soil preparation and sowing: cosmos prefers a light, well-drained soil, even poor, but not too moist. Choose a location in full sun. Loosen the soil to a depth of 15 to 20 cm, without adding too much fertiliser (soil that is too rich promotes foliage at the expense of flowers). Space young plants 30 to 40 cm apart.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
