Growing Sonata Mix Cosmos Garden Seeds

Sonata 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. Sonata Mix cosmos is just as popular indoors as out. Germination will take 14-21 days in full lighting. Lightly press 4-6 Sonata Mix cosmos seeds 24 inches apart into average, medium dry, and well-drained soil in full sun. Sonata 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. Sonata Mix cosmos has no serious insects, pests, or diseases. Sonata 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.

Cosmos bipinnatus, 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. Cosmos bipinnatus grows so effortlessly in the United States that it is considered an invasive species in several counties from California, Utah, and New Mexico and all the way up and down the Atlantic and Great Lakes states.
