Semi-double to double blooms in clear-white with crimped petals and tufted centers help set Cosmos Fizzy White apart from the others. Tall, well-branched plants are excellent for cut flowers, borders, and summer displays. Though Fizzy White looks dainty, it's a powerhouse of heat- and drought-tolerance, thriving in poor soils. Deadhead to extend bloom or let a few flowers go to seed for self-sowing.
