Black-eyed Susan vine is commonly grown in the Midwest as a season annual to provide color in a vertical setting. This plant, Thunbergia alata, is actually a tender evergreen perennial in the acanthus family (Acanthaceae) native from tropical East Africa to eastern South Africa that is hardy only in zone 9 and 10 (and is completely unrelated to Rudbeckia hirta, an herbaceous annual or short-lived perennial in the daisy family (Compositae) native to north America, also commonly called black-eyed Susan). Because it grows and flowers relatively quickly it is often used as an annual ornamental garden plant in cooler areas. It should be used with caution in frost-free areas as it has become invasive in many warm locations throughout the world.


cascade from a hanging basket (as well as grow up the hangers). Try combining black-eyed Susan vine with other aggressive vines such as morning glory or purple hyacinth bean. The orange or yellow flowers would contrast nicely with purple or blue flowers, such as salvia or ageratum, or purple-foliaged plants (such as Persian shield or purple heart) planted adjacent to the vine’s trellis. Use hot-colored flowers such as tall red zinnias, orange marigolds, or bright yellow celosia for a completely different look.Black-eyed Susan vines are reliably perennial only in USDA hardiness zones 10 to 11. Thus, in cooler areas, they are usually grown as annuals (removed from the garden after one growing season). But because black-eyed Susan vines are technically perennials (they come back year after year), you can put them in a container and bring them indoors for the winter if you're outside of their hardiness zones. Black-eyed Susan vines grown indoors may flower in the winter if they get ample sun and the temperature doesn't fall below 60 degrees Fahrenheit.

These vines will tangle themselves around the nearest support or spill over planter edges. They are perfect for hanging containers and flow just as easily over walls and raised garden beds. A lattice or metal fence makes a good choice for weaving your vines into a living wall, but these plants will clamber over just about anything—from a mailbox pole to an old tree stump. Black-eyed Susan vines bloom repeatedly from May through fall, and no deadheading (removing spent flowers) is required to keep them in bloom.Versatile, drought-tolerant and easy-to-grow, Black Eyed Susan adds a cheerful splash of color to the summer landscape. A native plant that attracts a variety of pollinators, Black Eyed Susan pairs beautifully with other prairie favorites like Purple Coneflower and Butterfly Weed. Its adapatable nature makes it a great choice for poor soils and tough conditions. All of the seed we carry at American Meadows is non-GMO, neonicotinoid-free and guaranteed to grow. Biennial.
