Rudbeckia, commonly known as Black-Eyed Susan, is an iconic perennial wildflower with a classic daisy-shaped face. Native to the US, this brilliant yellow bloom is extremely popular in gardens worldwide.
Rudbeckia blooms from June to late fall, reaching a height of 1 to 4 feet depending on the species. It grows best in full sun and moist, well-drained soil.
The blooms range from about 2-4 inches across; the centers can be yellow, brown, or black.
Non-native species of Rudbeckia include many hybrids that offer extended blooming times and higher flower counts.
Rudbeckia is an important nectar source for bees, birds, and butterflies.
Rudbeckia is relatively easy to cultivate and can be grown from seeds and cuttings.
The genus stems from Carl Linnaeus, who, in 1753, named the plant in honor of his teachers, Olof Rudbeck and Olof Rudbecksson.
In some parts of the US, Rudbeckia is considered a weed due to its robustness and vibrant colors.
Rudbeckia has been used medicinally—teas may be brewed, and an infusion used as an eyewash.
There are approximately twenty species of Rudbeckia native to North America.
Rudbeckia symbolizes justice, honor, and devoted love in the language of flowers.
