Often grown for their meaty seeds, Mammoth Grey Stripe Sunflower makes an even better centerpiece for your garden. Huge 12 inch blooms sit upon sturdy stalks that can grow 6 to 12 feet tall.

Since this plant needs space to develop its roots and hates being disturbed, the seed should be sown outdoors directly. Plant several seeds together 1" deep and 6" apart in rich, well-drained soil after the soil has warmed to 70-75 degrees F in late spring; the seeds will begin to germinate within 8-10 days. If necessary, cover the seeds with nets or a screen to prevent birds or animals from eating them as they sprout and develop. Keep the soil moist. Seedlings should be thin to very strong. As the seedlings grow, water them occasionally. When plants reach maturity, they can tolerate drought well, though they may need regular fertilizing to grow well. Be careful not to overwater, as this can cause disease. In addition to birds and bees, this plant attracts butterflies.
