Trumpet creeper is a rampant clinging deciduous vine native to the southeastern United States. Its orange, red, or yellow trumpet shaped flowers appear in late summer to early fall, attracting bees, butterflies and hummingbirds. The compound, pinnate leaves are typically dark green. Large bean-shaped fruits follow the flowers.
Trumpet creeper tolerates a wide range of soils in sun to light shade. It needs plenty of room to ramble and watch for root suckers and seedlings. It works well on a pergola, wall, large tree, or other substantial support. (info source: Learn2Grow.com)

|Trumpet creeper seeds are dormant upon ripening. In order to break the dormancy, they must be convinced that the environment is favorable for their survival. Only once dormancy is broken can the seeds be expected to germinate.
1. About 60 days before you want the seeds to begin to grow, mix them with moist and sterile soil or vermiculite.
2. Place the mixture in a plastic container and refrigerate at about 40 degrees Fahrenheit for 2 months.
The humidity in the container should be about 30 percent; this can be monitored by placing a digital hygrometer inside the container.
3. Fill a plant flat with seed starting mixture. Plant the seeds at a depth equal to half their width, and water until the mixture is just moist enough to stick to your finger. Move the flat to a location that receives indirect sunlight.
4. Water only when the seed starting mixture feels completely dry to the touch.
5. Transplant the young vines to their permanent growing location after all danger of frost has passed in spring.
6. Water when the top inch of soil is dry for the first three to four weeks after planting. Once established, the vines only need to be watered during very dry conditions.
