Cosmos sulphureus 'Bright Lights' features bright, glowing flowers, up to 2 inches across (5 cm), in shades of lemon yellow, gold, orange or vermillion-red from early summer until fall. Very attractive and eye-catching with profuse, joyful blossoms for weeks, this vigorous Cosmos creates a striking visual impact in the garden. Fabulous looking when combined with the blues of Mealy-Cup sage (Salvia farinacea) or the purples of Tall Verbena (Verbena bonariensis)!
- Fairly pest-free and low maintenance, add this charming and graceful plant to the landscape and you will be rewarded with abundant happy butterflies!
- Growing up to 3 feet (90 cm) high, this is an ideal addition to beds and borders, containers, cottage gardens, wild gardens and cutting gardens.
- Performs best in full sun, in average, medium moisture, well-drained soils. Dry and poor soils are tolerated, but rich, fertile soils should be avoided as the plant may grow taller and flop over. Do not over fertilize as it will promote foliage more than flowers and may also cause the plants to topple. This plant is fairly heat, humidity and drought tolerant.
- May be grown from seeds or live plants. Sow seeds outdoors after all danger of frost has passed or indoors 6-8 weeks prior to the last spring frost date.
- Pinching off dead blossoms will promote continuous blooming. If the flower heads remain, the cosmos will self-seed, but will not become a nuisance.
