Plant Bright Lights cosmos seeds in full sun. It's easy to grow in a variety of soils - tend towards the dry side. Its natural drought tolerance makes it a good candidate for xeriscaping. Plants grow to about 1m (3') tall, for the middle or front of a mixed border. Mix Bright Lights with dark blue and purple flowers like Blue Boy Centaurea or Rocket Larkspur Delphiniums for eye-catching contrast.
Direct sow after the last frost date. Several sowings will result in a very long bloom period. Cosmos can also be started indoors in late winter for transplanting after last frost, once daytime temperatures are above 10°C (50°F). Seeds will sprout in 3-10 days. Optimal temperature for germination: 21-25°C (70-75°F).
Sow seeds very shallowly only a few millimetres (1/8″) deep. Thin or transplant to 20-25cm (8-10″) apart.
