Plant these Mammoth Sunflower seeds outside after the danger of the last frost has passed. Mammoth sunflowers can grow up to 10-12 feet tall with flower heads 12-24 inches wide.
Sunflower plants prefer full sun and rich, well-drained soil.
When the seeds mature, they can be roasted for snacking, fed to wildlife, or served as a treat to your chicken flock. Remember also to save your seeds for the next Seed Swap!
Happy growing!
Minimum seed count - 25
