Novel cosmos resemble fluted cupcake wrappers.
Cupcakes Mix is as showy as Double Click with lighter-weight blooms held upright on stems. The light-colored, finely pleated blooms float above the foliage, reminding us of Degas’ paintings of ballerinas. A small percentage of flowers have lovely, tufted centers. Ht. 40-50". Ht. 40-50".

SOWING: Direct seed: After last frost, once soil temperature is above 60°F (16°C), sow seed thinly in rows, barely covering the seeds. Thin when the first true leaves appear. Tall varieties may benefit from some wind protection. Transplant: Sow seed thinly, barely covering, 5-7 weeks before setting out. Keep soil moist until emergence. When the first true leaves appear transplant into larger containers. Harden off and transplant outdoors after the last frost.
