Brown-Eyed Susan Seed Pack
Brown-Eyed Susan: Rudbeckia triloba
Rudbeckia triloba is an easy-to-grow native of the central-eastern United States and was commonly grown in 18th century flower gardens.
Brown-eyed Susan is grown as a biennial or a short-lived perennial and prefers full sun. It is easy to grow from seed and will self-sow and naturalize on open soil. Plants grow to 2-3' tall and 1-1½' wide. Golden yellow flowers 1-1½" in diameter with dark brown centers are produced from mid-summer to fall. The blossoms attract butterflies, and the seeds that follow are a favorite of goldfinches. Deer and drought resistant.
Seeds need a cold period to germinate, so place the seeds in a plastic bag with moist growing medium and place in the refrigerator for 30 days. Then, 6-8 weeks before the last frost date, sow seeds, and cover with ¼” of germination mix. Keep soil moist. Seeds germinate in 7-14 days at a soil temperature of 70°F. Alternately, direct sow seeds into the garden when daytime temperatures are consistently 60°F. USDA Zones 4-8.
