This packet of about one hundred Mammoth Grey Stripe sunflower seeds is perfect for planting a wildflower garden that will attract pollinators such as birds and bees. They're reliable and easy to grow, bringing beauty and biodiversity to your outdoor space.
Planting instructions: Space seeds about 6 inches apart in a shallow trench between 1 and 2 inches deep. In sandy soil, 2 inches deep is better. Cover and keep watered until seeds sprout in 7 to 10 days. When first true leaves appear (the second set of leaves); thin plants to about 2 feet apart. Depending on the variety, sunflowers will mature and develop seeds in 80 to 120 days. Sow a new row every 2 to 3 weeks to enjoy continuous blooms until the first frost. Sunflowers grow best in locations with full sun.
