Thunbergia (more commonly known as Black-eyed Susan Vine) is a native of Tropical Africa. It is a vining seasonal bloomer that can reach a spread of 8 feet wide. With evergreen leaves and orange or yellow blooms, this perennial is the right choice for hanging baskets, cascading color for combination planters, and trellises. Thunbergia bloom in the late summer and early fall as the days shorten. Adding these to your summer program can produce early fall sales.

Growing Tips

For best results with Thunbergia, we recommend using a constant feed program of 150-200 ppm N. Maintain a pH between 5.8 - 6.2.


Pinching is recommended 5-10 days after transplantation.


Hanging baskets should be spaced 18-24 inches. Space adequately to allow airflow and light penetration between the foliage of adjacent pots.

Height Control

Pinching is the best way to control height. An initial pinch is recommended, but additional pinching may be necessary to shape your final product.


Whiteflies, spider mites, and thrips are the biggest pest problems with Thunbergia.


Yellow Black Eye Susan are not prone to many diseases, but watch for botrytis while the days are short. This grey rot is usually associated with wet or humid conditions. You can prevent botrytis by allowing the plant to dry out between waterings, allowing for good airflow in your greenhouse, and spacing to allow the sun to penetrate to the soil level. The most common chemicals used to treat botrytis are Medallion and Banrot. Use them as a drench according to each label’s instructions.

Planting Yellow Black Eye Susan Liners

  1. We recommend planting 4-5 starter plants per 10” basket. Use a well-drained soil in your baskets and plant your starter plants deep, allowing the ellepot to be completely covered by the soil. If you are planting 4” pots, 1 plant per pot should be sufficient if you have enough time. Plant it directly in the middle of your pot.
  2. Pinching is recommended 5-10 days after transplantation. A second pinch may be necessary depending on the size and shape of the final pot.

Rooted Cuttings

Cuttings vary in size between different plant families. These rooted starter plants will arrive ready to be transplanted in to your final container. If they are to be used in a landscape application, you will need to establish them in a 4 inch pot or an 1801 before planting outside.
