By Ellen Brown

Botanical Name: Rudbeckia
Life Cycle: perennial
Planting Time: spring or fall
Height: 1' to 9' depending on type
Exposure: full sun to light shade
Soil: average to rich, evenly moist, well-drained soil
Hardiness: zones 4 to 10 depending on variety
Bloom Time: summer to fall
Flower: yellow to red-brown and rusty orange daisy-like petals with brown or black centers.
Foliage: green
Propagation: seeds or division
Suggested Use: beds, borders and native plantings
Growing Hints: Purchase plants in spring or start them from seeds sown directly into the garden in the spring or fall. Seeds can also be sown in pots in early spring or fall and set outdoors in a protected location. The exception is Gloriosa seeds. They should be sown either several weeks before the last frost if sown indoors, or two weeks before the last frost date if sown outdoors. Press seeds gently into the soil, but don't cover them. They need light to germinate. Once established, plants are quite drought tolerant and readily reseed themselves. Biennial varieties tend to alternate weak and showy years.
Interesting Facts: Rudbeckia are Native American wildflowers and are wonderful for attracting birds such as chickadees cardinals, sparrows and nuthatches.
