Description

This giant among sunflowers is a fast grower whose single stalk can reach 12' tall and produces one 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 bloom 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.
