This exclusive mix from Johnny's Selected Seeds was bred specifically for cut-flower performance, and it shows. The branching habit means you get multiple stems per plant rather than a single dominant flower, and pinching encourages even more stems for longer harvests. Direct seeding after the last frost gives you blooms in 60-75 days, but starting seeds indoors just 2-3 weeks before planting out can deliver even earlier flowers if you're patient with the transplanting process. The compact growth habit keeps plants tidy while their flowers can be harvested at any stage from first color through full bloom, depending on whether you're designing tight arrangements or dried displays.
Summer Breeze Sunflower is bred and celebrated as an excellent cut flower. The branching growth habit produces multiple stems per plant, each topped with bloom, making it exceptional for fresh arrangements. Flowers can be harvested at tight bud stage for longer vase life, at first color for looser, more naturalistic looks, or when almost completely open depending on your design preference. The variety is equally suited to drying; hang fully open flowers or use silica gel to preserve them for winter arrangements.

Sow seeds into 72 or 50-cell flats 2-3 weeks prior to planting out. Sunflowers dislike root disturbance, so handle seedlings gently when transplanting. Keep soil moist and warm until germination occurs.
Transplant seedlings outdoors after the last spring frost when soil has warmed. Space plants 18 inches apart. Harden off seedlings gradually by exposing them to outdoor conditions before planting.
Direct seed is recommended. After the last spring frost, sow seeds 1/2 inch deep directly into garden soil. Direct seeding often produces sturdier plants than transplanting, though succession seeding indoors and out can be a successful strategy for getting early and continuous blooms.
Flowers can be harvested at three distinct stages depending on your use. Harvest tight, just when color first shows, for the longest vase life in fresh arrangements. Cut when almost completely open for a fuller, more open look in bouquets. For drying, wait until flowers are completely open, then hang them or use silica gel to preserve them.
Pinching branching varieties is recommended to encourage fuller branching and longer, more abundant stems for cutting. This early-season pinch redirects energy from a single main stem into multiple flowering branches.
