Start indoors in a warm, well-lighted area about 10 weeks before planting outdoors. Sow seed 1/8" deep into individual containers filled with seed-Starting formula. Keep moist.
How to Grow
Seedlings emerge in about 21 days at 70-75°F. Before transplanting move to a sheltered area outside for a week. Select a sight in full sun to light shade to transplant your seedlings. Although rudbeckia tolerates a wide range of soil conditions, it grows best in rich, well-drained soil. Taller cultivars may need staking.
Rudbeckia provides a long season of bloom for the middle or back of the border. Try shining rudbeckia in masses for a striking landscape feature. Naturalize tall-growing rudbeckia in a wildflower meadow. Or use them as a screen or hedge. The flowers of all types are great for fresh arrangements.
