Why Grow Cosmos Flowers?

Cosmos is a versatile plant, whether growing in containers, bedding displays or in a cottage garden style. Suttons have an incredible Cosmos seed range. Cosmos flowers take many forms and colours. 

There is the classic ‘sensational tall’ a lovely tall cosmos for borders. Or for a more twilight garden try ‘Double white Knight’. ‘Fizzy pink’ will brighten up any border or pot.

Growing Cosmos From Seed?

The half-hardy annual is best sown during February and March under glass for flowers from July to September. They can also be sown outdoors from March to May for flowering during late summer.

When the soil starts to warm up in the spring, start preparing your growing bed or border. Lightly forking out the air pockets and rake the soil level. 

Cosmos is loved by Loved the Butterfly and important to encourage these beautiful pollinators. They make great centrepieces in a colourful seasonal container.

Cosmos Seed Germination

Cosmos seeds should germinate within 5 to 10 days. Transplant the seedlings into trays and grow on. The Cosmos plants need to get used to outside conditions before planting out at 40cm apart, in an open sunny position.
