The satin-textured petals edged in deep mahogany against a pure white background create an almost jewel-like appearance that commands attention. Each plant generates prolific flowers throughout the season, making it far more productive than many ornamental varieties. The feathery foliage has an airy, delicate quality that softens garden borders while the blooms themselves remain bold and striking. For gardeners seeking cut flowers that arrange beautifully or simply want easy color that attracts pollinators, this cultivar delivers abundance without fussiness.
Picotee Cosmos works beautifully as a cut flower, where the mahogany-and-white coloring brings visual impact to fresh arrangements. In the garden, it excels as a border plant, adding height and continuous color from mid-summer through fall. Its pollinator-friendly nature also makes it valuable for anyone designing a garden to attract bees, butterflies, and other beneficial insects. Container gardeners appreciate its compact 24-inch height and abundant flowering habit in pots and raised beds.

Start seeds indoors 4-6 weeks before your last frost date, sowing at 65-80°F. Seeds should germinate within 7-10 days. Keep soil moist but not waterlogged during this period.
Harden off seedlings over 7-10 days by gradually exposing them to outdoor conditions. Transplant after all frost danger has passed. Space plants 12 inches apart with 18 inches between rows.
Direct sow seeds outdoors after the last frost date when soil has warmed to at least 65°F. Press seeds lightly into soil without covering, as they need light to germinate.
Pinch back young plants when they reach 6 inches tall to encourage bushier growth and more prolific branching. Deadhead spent flowers regularly to extend blooming throughout the season. No severe pruning is necessary, though you can cut stems back by one-third in mid-summer if plants become leggy.
