Cosmos varieties

Pink and white cosmos
Widely available varieties of Cosmos bipinnatus
‘Purity’ (100cm/39 in)
An old single white, but still effective in September light when it looks gloriously fresh.

‘Sensation Mixed’ (120cm/4ft)
A mixture of single colours in shades of pink-red through to white. It’s tall and stately so not as useful in smaller gardens.

‘Sonata Series Mixed’ ( 60cm/2ft)
A shorter cosmos, but with equally large flowers, so this is good at the front of the border, or in a container, or grow for cutting. Sarah Raven has an all-pink version ‘Sonata Pink’.

‘Sweet Sixteen’ (90cm/3ft)
This picotee-edged cosmos has pale petals edged in deep-pink and each flower has some extra petals at the heart, giving each flower a frilly look. ‘Sweet Kisses’ seems very similar.

‘Seashells’ (120cm/4ft)
This taller cosmos comes in a mixture of pinks and whites, but the petals are almost cylindrical or fluted.

‘Cupcakes’ (up to 90cm/3ft)
This is very special, with dished flowers consisting of fused petals that look like cupcake cases. The whites turn blush-pink and many of the flowers have extra petals. Bred by Thompson & Morgan.

‘Hummingbird’ (45cm/18in)
A very new Dutch-bred series with fluted petals on larger flowers. There’s a pink and a white and this is far better than ‘Seashells’.

‘Daydream’ (90cm/3ft)
A white cosmos with powder-pink centres - adored by flower arrangers.

‘Double Click’ (100cm/39in)
This Dutch-bred series was the first to contain semi-doubles and doubles and they look very aster-like. However they do get very heavy-headed in summer rain, and can flop. In good summers they add much to the vase and garden and the flowers last for a long time because thy can’t be pollinated.

‘Xanthos’ (60cm/2ft)
Soft-yellow blooms on compact plants, so perfect for the front of a border or a container. Very new and very well-thought of, this May-flowering cosmos bred in Holland has been given a Fleuroselect Gold Medal this year. You can buy seeds or plugs.

'Apollo' (60cm/2ft)
A brand new British-bred variety, these cosmos flowers come in shades of pink, white and purple.
