Colorful Cosmos Cultivars: A Guide to Stunning Varieties for Your Garden

Cosmos are insanely easy from seed—"If you have trouble growing Cosmos, take up golf!" (Wildseed Farms). Introduced to English gardens in the early 1800s from Mexico; Spanish priests named them for the Greek "cosmos" (harmony/ordered universe) due to precisely placed petals.

Don't start too early indoors—leggy, weak plants result. Direct sow: press darker, thicker seed point down ¼ inch, tail exposed. Feathery foliage emerges in days; some bloom within weeks at just inches tall. Never fertilize—they don't need it. Full sun, airy foliage, great background plants. With today's shapes, colors, and sizes, there's a perfect Cosmos for every garden.
