Sensation 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. Sensation Mix cosmos is just as popular indoors as out. Germination will take 14-21 days in full lighting. Lightly press 4-6 Sensation Mix cosmos seeds 24" apart into average, medium dry, and well-drained soil in full sun. Sensation 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. Sensation Mix cosmos has no serious insects, pests, or diseases. Sensation Mix cosmos seeds mature in 49-63 days as 36" tall shrubby uprights with a 12-24" spread of 2" daisy-like blooms.
