Growing Bright Lights Cosmos Garden Seeds

Bright Lights cosmos seeds are popularly sown outdoors directly after the frost. But for earliest spring blooms, begin seeds indoors 6-8 weeks prior and harden off to a sunny place in the garden or decorative planter. Bright Lights cosmos is just as popular indoors as out. Germination will take 14-21 days in full lighting. Lightly press 4-6 Bright Lights cosmos seeds 24" apart into average, medium dry, and well-drained soil in full sun. Bright Lights cosmos is a hardy full sun performer known to be low-maintenance and tolerant to heat and drought. Do not overwater because cosmos will suffer in overly saturated and poorly drained gardens. Plants may reseed for next season, but may do so too aggressively to the point where it becomes invasive. Bright Lights cosmos has no serious insects, pests, or diseases. Bright Lights cosmos seeds mature in 56-63 days as 36" tall mounded shrubs with a 12-24" spread of 2-3" daisy-like blooms.

Cosmos sulphureus, or more commonly known as just Cosmos, is native to the arid and warm climates of Mexico, but has since been naturalized throughout most of the world's similar climates. Although not as aggressive as other varieties of cosmos, Cosmos sulphureus grows so effortlessly in the United States that it is still considered an invasive species in many counties along the lower half of the states.
