MOST cosmos are sun-loving annual flowers that bring us a summer-long season of golden-eyed daisy flowers set against fresh green, feathery foliage.
Easily raised from seed sown in spring, the plants have a gentle and relaxed style that fits well with other annual and perennial flowers, as well as shrubs. They make superb cut flowers and shorter varieties can also be grown in large containers.
Cosmos and climate
In most of the country, seed of cosmos can be sown outside in late spring where you need the plants to flower. Wait until after the last frost date in your area, then sow the seeds in rows according to the guidance on the seed packet.
