Black eyed susan vine (Thunbergia) is perennial in USDA plant hardiness zones 9 and above, but it grows happily as an annual in cooler climates. Although it isn’t related to the familiar black-eyed susan (Rudbeckia), the vibrant orange or bright yellow blooms of black eyed susan vine are somewhat similar. This fast-growing vine is also available in white, red, apricot, and several bi-colors.

Are you interested in container-grown Thunbergia? Growing black eyed susan vine in a pot couldn’t be easier. Read on to learn how.

How to Grow Black Eyes Susan Vine in in a Pot

Plant black eyed susan vine in a large, sturdy container, as the vine develops a hefty root system. Fill the container with any good quality commercial potting mix.

Container-grown Thunbergia thrives in full sun. Although potted black eyed susan vines are heat tolerant, a little afternoon shade is a good idea in hot, dry climates.

Water black eyed susan vine in containers regularly but avoid overwatering. In general, water container grown Thunbergia when the top of the soil feels slightly dry. Keep in mind that potted black eyed susan vines dry out sooner than vines planted in the ground.

Feed potted black eyed susan vine every two or three weeks during the growing season using a dilute solution of a water-soluble fertilizer.

Watch for spider mites and whiteflies, especially when the weather is hot and dry. Spray the pests with insecticidal soap spray.

If you live north of USDA zone 9, bring potted black eyed susan vines indoors for the winter. Keep it in a warm, sunny room. If the vine is extra-long, you may want to trim it to a more manageable size before you move it indoors. 

You can also start a new black eyed susan vine by taking cuttings from established vines. Plant the cuttings in a pot filled with commercial potting mix.
