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. Set plants in rich, well-drained soil in full sun, although they tolerate a wide range of soil conditions, from moist to dry. Divide overcrowded plants in spring, or after flowering in late summer or early fall. When they are happy, rudbeckia will knit together into a vigorous grondcover that will choke out weeds.
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.
