This cultivar of Helianthus annuus thrives in full sun and actually prefers lean conditions, making it surprisingly low-maintenance once established. Direct sow after soil warms to 55°F, space plants 3 inches apart in rows 30 inches wide, and you'll be rewarded with flowers ready to cut in their prime.

Concert Bell Sunflower performs beautifully as a cut flower, with blooms that last longer when harvested in the morning just after opening. The real reward comes after flowering: cutting the main central head actually triggers side-shoot production, extending your bloom season. Gray and white striped seeds develop on mature heads, making this variety attractive both while growing and for seed saving.
This sunflower excels as a cut flower for fresh arrangements, and because cutting the central head promotes abundant side-shoot flowering, a single planting yields multiple harvests. For seed savers, the gray and white striped seeds are particularly noteworthy and worth harvesting at season's end.

Direct sow in the garden as soon as the soil warms to at least 55°F. Space plants 3 inches apart in rows spaced 30 inches wide.
For cut flowers, harvest in the morning just after the blooms open, using a clean knife. Place stems immediately in a clean vase with a few drops of chlorine bleach in the water to extend vase life. For seeds, wait until the bracts begin to shrivel, then cut the entire head and hang it upside down in a barn or shed to dry completely.
Cutting the mature central flower head will actively promote side-shoot flower production, extending your bloom season. This is not just acceptable but encouraged: harvesting encourages the plant to produce multiple additional flowers.
