Fizzy White Cosmos is an early, prolific cosmos with distinctive tufted white centers that sets it apart from standard cosmos varieties. This open-pollinated cultivar blooms prolifically across hardiness zones 2 through 11, reaching maturity in 75 to 90 days from seed. Its compact growth habit makes it at home in borders, containers, and cutting gardens, while the unique texture of those tufted centers gives it genuine character. Hardy enough to grow almost anywhere, this cosmos thrives in warm soil and full sun, asking little beyond well-draining earth with a soil pH between 5.5 and 7.5.

Early-blooming white cosmos with strikingly unique tufted centers that make each flower a conversation piece in the garden. The compact growth habit produces abundant blooms over a long season, and gardeners prize it specifically for cutting; the flowers hold their visual appeal from the moment petals just begin to open. Deadheading extends the show all summer long, rewarding a little attention with continuous color. Sow after the last frost and you'll have stems worth cutting within 75 to 90 days.
Fizzy White Cosmos excels as a cut flower. The tufted centers and prolific bloom production make it a reliable choice for filling vases and arrangements throughout the season. Its compact form also works well in containers and garden borders, bringing that delicate cosmos charm to smaller spaces.
No timeline data available yet for this variety.
Sow seeds into 50-cell plug flats or your preferred seedling container 5 to 7 weeks before your last frost date, covering seeds lightly. Maintain temperatures between 65°F and 80°F for germination. Harden off seedlings by gradually exposing them to outdoor conditions before transplanting.
Transplant hardened-off seedlings outdoors after all danger of frost has passed. Space plants 9 inches apart in full sun. Pinching growing tips at transplant time encourages branching.
Direct sow seeds outdoors after the last frost date, once soil temperature reaches 60°F (16°C) or higher. Cover seeds lightly with soil and keep moist until germination.
Cut flowers for arrangements when petals are just opening but not yet fully flattened, harvesting in the cool morning hours for maximum vase life. Remove spent blooms regularly to encourage more flowering.
Pinching seedlings or young plants encourages branching and a bushier growth habit. Deadheading spent flowers is essential throughout the season to maintain continuous blooms and prevent the plant from setting seed.
