Sonata White Cosmos is a compact cosmos cultivar bred for earlier and more abundant blooms than taller varieties. Its pure white flowers emerge reliably between 56 and 84 days from seed, flowering continuously from summer through fall. Growing to just 24 inches tall with a 18-inch spread, this cultivar thrives on neglect once established, tolerating drought with grace while attracting pollinators throughout the season. It's an outstanding choice for gardeners seeking a low-maintenance flower that blooms prolifically in full sun without fussy feeding or constant watering.

Sonata White produces pure white blooms on a remarkably compact plant, rarely exceeding 24 inches, making it far more suitable for smaller gardens and containers than traditional cosmos. The cultivar's drought tolerance and resistance to powdery mildew mean you can plant it in spring, water it in during establishment, and then mostly ignore it. Flowers arrive early and persist through the first frost, delivering months of pollinator-friendly color with virtually no intervention required.
Sonata White Cosmos is grown primarily as an ornamental flower for borders, cottage gardens, and containers. The pure white blooms provide bright contrast in mixed plantings and work well in fresh-cut arrangements, though they're most valued for their ability to fill garden spaces with color and movement throughout summer and fall.
No timeline data available yet for this variety.
Start seeds indoors in pots 4 to 5 weeks before your last spring frost. Keep the soil temperature around 60 to 75 degrees Fahrenheit for best germination. Sprouts should emerge within 3 to 10 days.
Transplant seedlings outdoors after the last spring frost has passed, spacing them 18 inches apart to allow mature plants room to spread.
Direct sow seeds in spring after all danger of frost has passed, pressing seeds lightly into prepared soil.
