The black oil seeds (“oilers”) have very thin shells, easy for virtually all seed-eating birds to crack open, and the kernels within have a high fat content, extremely valuable for most winter birds. Striped sunflower seeds have a thicker shell, much harder for House Sparrows and blackbirds to crack open.

Mother Nature made sunflowers (Helianthus annuus) as simple as a child’s drawing — green stalk, yellow petals, dark seeds — but modern gardeners have many more choices, with hundreds of cultivars in dozens of colors. … So-called black sunflowers are simply dark-toned garden cultivars.
