Growing Cosmic Mix Cosmos Garden Seeds

Cosmic Mix 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. Cosmic Mix cosmos is just as popular indoors as out. Germination will take 14-21 days in full lighting. Lightly press 4-6 Cosmic Mix cosmos seeds 24 inches apart into average, medium dry, and well-drained soil in full sun. Cosmic Mix 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. Cosmic Mix cosmos has no serious insects, pests, or diseases. Cosmic Mix cosmos seeds mature in 49-63 days as 20-24 inch tall mounded shrubs with a 24-36 inch spread of 2-4 inch daisy-like blooms.

Cosmic Mix cosmos debuted as a 2000 All-American Selections Flower Winner for its "abundant bright orange 2 inch blooms", "basically pest and disease free", and "a no fuss annual that will thrive on minimal care." Although not as aggressive as other varieties of cosmos, Cosmos sulphureus grows so effortlessly in the United States that it is considered an invasive species in many counties throughout the lower half of the states.
