Harvesting Mammoth Grey Stripe Sunflower

Mammoth Grey Stripe sunflowers develop edible seeds. Simple steps for seed collection: The birds and other small critters go crazy for these seeds and will eat them if they aren’t collected promptly upon maturation. Use a mesh sack that can be secured over the flower and cinch it over the flowerhead once the petals have faded. For this variety, you may need to use a stable ladder to reach the giant flower heads. Over the next month, the seeds will mature and fall into the bag for easy collecting!

These tall beauties can be cut flowers for seasonal bouquets of bright yellow. When they are in full bloom, snip off the stem one to one and a half feet below the bloom. Tie a few stems together with a rubber band and suspend them upside down in an area with ventilation for dried flowers in 2-3 weeks!
