The story
Sunflowers were domesticated in what is now the eastern United States about 4,000 years ago by Indigenous farmers, who bred the giant single heads for seed, oil and dye; Hidatsa and Mandan women grew them at the field's edge and the Hopi used them in ceremony. Russians bred the oil types, and the seed came home.
Planting
Full sun, any decent soil; sow seed directly after frost, an inch deep. Giant types need staking or shelter from wind.
Growing
Water deeply in dry spells and keep weeds down while young; after that it looks after itself. Feed little or the stalk outgrows the head.
Harvest and use
Cut heads in autumn when the back turns yellow and the seeds fill; hang to dry out of reach of birds, then rub out the seed. Roast, press, or feed the birds.
What to watch for
Birds and squirrels at harvest, sunflower moth, and rust on leaves.
