PACKET INSTRUCTIONS: May start in flats 3-4 weeks before last frost & transplant, but better to start directly in good, non-acid, well drained garden soil after danger of frost is past. Prefers a light loam. Does best, if well dug. Needs full sun, for best display, fertilize it well, lime if necessary, and make sure it doesn't get dry enough to wilt. Stakes and string around the edges and criss-crossing the center of the bed will help prevent the plants from falling over as the heads mature.
BOTANICAL NAME: Helianthus annuus
DESCRIPTION:Black-seeded type bred for big yields of small seeds high in oil. Plants get about 6 ft tall and have the familiar bright yellow flowers, smaller than ornamental types but still wonderful to see planted in a whole bed. Flowers turn downward when the seed is ripe to protect from birds, moisture, etc.
