Cosmos is totally unselfish in providing masses of colour over a long season, while requiring very little effort by the gardener. That is why cosmos is such a garden favourite for beginners and experienced gardeners. Cosmos seeds can be started indoors or direct seeded. This annual comes in various colours and is available as a single or double flower. The 1m (3.3′) high plants can quickly fill your garden with delightful colour.
Bloom time: Late spring through mid-autumn.
