Description

The Kew Pollinators range of seeds from Thompson and Morgan has been specially created alongside the experts at Royal Botanic Gardens, Kew to attract and support a wide range of pollinators, including bees, butterflies and beetles, as well as a number of other important pollinating insects. Helping these pollinators to thrive is hugely important for our eco-system as a whole and these seeds, in their striking packaging inspired by artwork from the Kew archives, will help to create the environment which they need to thrive, with varieties chosen to help a wide range of pollinating insects, including some night flowering plants to help moths which also play an important part in our gardens.

Tall, ferny foliage topped with bright, single blooms that range from white glacial white to carmine pink. This cheery annual provides a bold splash of colour to the back of borders, mingling beautifully with summer flowering perennials. Their strong stems and good vase life make Cosmos an excellent choice as a cut flower, but pollinating insects will thank you for leaving some in the border where they provide a valuable source of nectar. Cosmos bipinnatus is quick and easy to grow, virtually looking after itself once established. Height: 120cm (47"). Spread: 60cm (24").

Sowing

Sow Cosmos seed from March to May at a depth of 3mm (?") in a good quality seed compost, and cover the seeds with a very fine sprinkling of vermiculite. Place the seed tray in a propagator at a temperature of 18-25C (64-77F) or seal it inside a polythene bag. Keep the soil damp but not wet. Do not exclude light as this aids germination which usually takes 7-15 days.

When seedlings are large enough to handle, transplant into 7cm (3") pots and grow them on in cooler conditions until large enough to plant outdoors. When Cosmos plants are well grown and all risk of frost has passed, acclimatise them to outdoor conditions over 7 to 10 days. Transplant outdoors in full sun in any moist, well drained soil at a distance of 45cm (18") apart. Pinch out the growing tip of each stem when transplanting to encourage stems to branch and produce more Cosmos flowers.

More Info
When growing Cosmos plants, water regularly until they are fully established. Deadhead faded Cosmos flowers regularly to encourage more blooms to be produced throughout the summer.
