fast into strong single stems topped with golden blooms, then fill with the small, oil-rich seeds that songbirds love and you can roast for a snack. They are easy, dramatic, and endlessly useful. Who it's for Wonderful for beginners, families, and anyone who loves birds. Black oil sunflowers are among the easiest and most satisfying plants to grow from seed, shooting up quickly to delight kids, and their seed heads make a natural bird feeder come fall. How & when to plant Sow the seeds directly after your last frost, once the soil is warm, planting them about an inch deep in full sun. They sprout quickly, in about 7 to 10 days. Space plants about 6 to 18 inches apart depending on how large you want the heads, giving them a sunny, sheltered spot since the tall stems can catch the wind. Our Sunflower growing guide has the details. Growing & care Sunflowers are easygoing. Give them full sun and regular water while young, then let them race skyward. Tall plants may need staking in exposed gardens, and a little support helps once the heavy seed heads form. They rarely need feeding and shrug off summer heat. Harvest For seeds, let the flower heads mature until the backs turn brown and the seeds are plump, then cut the heads and dry them in an airy place. Rub the seeds free to roast for snacking or to offer the birds. Or simply leave the heads standing in the garden as a natural winter feeder. Benefits & uses Black oil sunflowers are a triple treat: bright cut flowers in summer, a feast of nutritious seeds for you and the songbirds in fall, and a magnet for bees and pollinators while in bloom. They bring height, color, and life to any sunny garden.
