Continuous Re-Bloom

Dead-Heading Not Necessary

Heat Tolerant

Long Blooming


Maintenance Notes

Easy to care for.  No deadheading is necessary.

Uses Notes

Great for use in landscapes and containers.  If grown in a hanging basket it will climb the chains, which can look pretty cool.  Given something to climb on in landscapes and upright containers, it will do so, otherwise it will sprawl and potentially climb nearby plants.

Pinching and Growth Regulators

Pinch once 7 to 10 days after transplanting. An additional 1 to 2 pinches may be necessary for larger pot sizes. Chemical PGR's have not proven to be effective. Using proper temperatures, allowing soil to dry slightly between watering, providing high light levels, and spacing the plants will produce a good crop.

Pest and Disease Management

Standard pest and disease practices as indicated in notes. Watch for aphids, whiteflies, spider mites, and leafminers. Treat as needed. Rhizoctonia and Pythium can also be problematic, control watering and treat as needed.

Grower Tips

-Use a light, well drained soilless medium.
-Temperatures below recommended temperatures will significantly slow plant growth.
-Do not allow soil media to dry completely or the plant to wilt repeatedly or leaf burn will occur.
-Excessive phosphorous and ammoniacal nitrogen will cause soft, unwanted vegetative growth. Provide both in limited quantities.
-If new growth is chlorotic, add chelated iron to the feed program.

-Requires relatively high light levels and warm night temperatures. In areas with low light levels in early Spring, Thunbergia is best planted as a mid to late Spring and Summer crop.
