Low-maintenance and lovely, black-eyed Susan flowers start opening in early summer and keep on coming until fall frost. Most black-eyed Susan plants are perennial, although some are short-lived at best. Happily, many black-eyed Susans self-sow readily, ensuring a continued presence in the garden.
Botanical Name: Rudbeckia
Common Name: Black-eyed Susan
Hardiness Zones: 3 to 10
Size: 24 to 36 inches tall and wide; blooms 2 to 3 inches in diameter
Bloom Time: Late spring through early fall
On average, black-eyed Susan plants grow 24 to 36 inches tall and wide. If plants are happy, they can spread somewhat aggressively with underground stems and self-sowing. Limit the spread by dividing clumps every four to five years. Snipping spent blooms in fall prevents self-seeding. But if you leave faded flowers in place, they’ll add winter interest to the landscape and attract seed-eating birds.

This perky perennial, especially Rudbeckia fulgida, is drought-tolerant once established.
Black-eyed Susan plants boast sturdy constitutions, offering winter hardiness in Zones 3 to 10.
Planting Black-Eyed Susan
When to Plant Black-Eyed Susans
It's best to plant perennial Rudbeckia in early fall so they can acclimate to their new environment, but they can also be planted in mid-spring.
Give this bright bloomer a spot in full sun, although in hottest regions, a little afternoon shade won’t hurt. Plants survive in a partly shade location, but flower number will be reduced. Black-eyed Susan isn’t picky about soil and thrives in average soil that drains well.
Water newly planted black-eyed Susans until they’re steadily showing new growth, then gradually reduce moisture.
