Planting and care
Black-Eyed Susan Vines are only hardy in USDA zones 9-12.
They should be grown in a spot with full sun or very light shade,
except in hot summer regions where they will require shade during the afternoon.
In the garden, Thunbergias should be planted in humus rich, evenly moist, well-drained soil that has been supplemented with a generous amount of compost at planting time, or in a good quality potting soil if they are grown in planters.

Caring for Thunbergia Alata
- Black Eyed Susan Vines are very easy to grow.
- Grow the plants in full sun to light shade. In hotter regions, plant where they will receive afternoon shade.
- Grow Thunbergia in rich soils to help fuel growth. Prior to planting, mix in ample amounts of compost.
- Add a general purpose fertilizer every 4-6 weeks. Thunbergia plants do not tolerate droughts very well.
- Keep the soil well watered, especially when young, and during hot and dry weather. If grown in containers, be vigilant that they do not dry out.
- Keep young plants well weeded, until they get established and begin to climb. Thunbergia plants can be trimmed, as needed.
- Plants need the support of a fence, trellis or post. Train young plants to reach the support.
Typical uses of Thunbergia Alata
Special features: Used mainly as an ornamental plant, Thunbergia alata makes a good screen when used to cover unsightly dead trees or walls. It needs some support, as it cannot cling. Use fences, trellises, arches, arbours and pillars or a lightly shading tree.
(Pergolas would probably be too big.) Alternatively, plant this creeper in groups as a ground cover, or on a bank or terraces where it can trail downwards. Hanging baskets are also a possibility.
Culinary use: NA
Ornamental use: Trellises, arbors, fences or other structures around the home. Also effective in hanging baskets where the vine can twist around the basket supports or in patio containers with a small trellis or obelisk buried in the container.
Medicinal use: NA
