Helianthus annuus & cucumerifolius (Sunflowers) - Planting: Sow seeds outdoors ½" deep and 6" apart in rows 24-36" apart after the last frost. Successive plantings will provide continual blooms throughout the summer. Seeds germinate in 10-14 days. Prefers full sun to light shade and well-drained rich soil.

Saving Seed: Sunflowers will cross-pollinate and must be separated by ½ mile to ensure pure seed. Harvest the heads when they have completely filled out, lost all of their petals and the backs begin to turn brown. It may be necessary to cover heads to protect them from birds. Allow to dry in a protected area away from birds and then shell by hand.
