SOWING: Transplant (recommended) - Sow into 72 to 50-cell plug flats 5-7 weeks before last frost. Cover seed very lightly as light is needed for germination. Harden off seedlings and transplant out after danger of frost has passed. Bottom water or mist to avoid covering seed. Direct seed - Surface sow 2 weeks before last frost. Heat and drought tolerant once established. Pinching not required. Reseeds.
LIGHT PREFERENCE: Sun.
PLANT HEIGHT: Varies.
PLANT SPACING: 12-18".
HARDINESS ZONES: Zones 9-10. Best grown as an annual.
HARVEST: Fresh: before blooms are completely open. Dried: when blooms are completely open.
SOIL REQUIREMENTS: Average, well-drained soil. Tolerates poor soil.
USES: Excellent cut flower. Beds, pots, back of borders, or wild, meadow, and cottage gardens.
Note: Rudbeckia requires long days to initiate flowering and will continue to produce some, smaller blooms into the fall but on shortened stems of reduced quality. Deadheading increases blooms during summer production.
