Rudbeckia – Black Eyed Susan




There are many varieties of Rudbeckia – I’ve yet to meet one that I didn’t like! Sturdy perennials with cheerful flowers, most are well-adapted to Oklahoma’s challenging climate.

Henry Eilers (Rudbeckia subtomentosa)

$5 for 3” re-used plastic pot

‘Henry Eilers’ is a unique and delightful native perennial with quilled, yellow petals encircling a brown dome-shaped center. Makes a fantastic cut flower. Summer bloomer, grows 3-6’ tall, drought tolerant, attracts butterflies. Full sun.

Named after a well-known nurseryman who discovered this cultivar growing in a wild patch of prairie next to railroad tracks in southern Illinois.

I have the regular Henry Eilers that grow 3-5’ tall, and a “dwarf” version– not a big difference. Add a note to your order if you prefer one or the other.

Brown-Eyed Susan (Rudbeckia triloba)

Named for its tri-lobed leaf. If I were forced to choose a favorite amongst all the rudbeckia, I would have to choose this one! Carefree, bushy plants bloom in August or September with an explosion of small, bright yellow flowers. Beautiful bouquet filler. Native wildflower, biennial or short-lived perennial, often self-seeds. 2-4’ height. Partial sun.

Great Coneflower (Rudbeckia maxima)

This giant of a flower will catch the eye of anyone within sight of it! The large, blue-green leaves at the base of the plant look a bit like cabbage leaves, earning it the nickname of Cabbage Leaf Coneflower.  The flower stalks will reach 4 or 5 feet in height, and are topped by deep yellow flowers with a brown center cone. A perennial native to Oklahoma, it prefers full sun and medium-dry soil. Butterflies and bees appreciate its blooms in summer, and birds will enjoy feeding on the seeds in the fall. Its roots are rhizomatous, so it will form colonies and slowly spread; it starts off the first year with just a few flower stalks, then increases year by year. An absolute favorite on our block.

Sweet Black-Eyed Susan (Rudbeckia subtomentosa)*

Long-lived perennial, with numerous 3” flowers. A tough prairie plant, it is able to tolerate wind and poor soils. Full/partial sun. Late summer/fall blooms.

Orange Coneflower (Rudbeckia fulgida)*

Orange Coneflower has large, daisy-like flowers. Plants grow in a mounded-profile and can form colonies in large plantings on sunny locations with medium-dry to medium-wet soil. Consistent moisture & good circulation will help it to get established. Mid-summer to fall blooming. Deer resistant. Full/partial sun, 3’ height.

*The Sweet Black-eyed Susan & the Orange Coneflower look similar when small, and I lost the labels on them. I’m pretty sure I can tell which is which, but if you order one of them, you just might get the other one. They are all beautiful, though, so you can’t lose J
