This giant among sunflowers is a fast grower whose single stalk can reach 12' tall and produces one Mammoth 10"-12" flower! Not fussy about soil, it's very easy to grow and drought tolerant. Grow in a tight row to make an attractive screen. Sow monthly for continual blooms into fall. Edible, gray-striped seeds invite birds in the fall (if you don't eat the seeds first!). Edible, bittersweet petals make a sunny garnish on salads and appetizer plates. Attracts pollinators.

When to sow outside: RECOMMENDED. 1 to 2 weeks after your average last frost date.

When to start inside: 2 to 4 weeks before your average last frost date. Sunflowers are sensitive to root disturbance; sow in biodegradable pots that can be planted directly in the ground.
