Are we talking about the same plant?
From BRAVE Summerizer AI:
Trumpet vine (Campsis radicans) is a native North American plant with glossy dark green elliptical leaves that grow up to 15 inches long, with seven to 11 serrated leaflets. It has clusters of trumpet-shaped red, orange, or yellow flowers that appear during the summer months and reach around 1 to 3 inches long before giving way to bean-like seed capsules.
Trumpet vine is often cultivated for its attractive, reddish orange flowers but can escape cultivation, sometimes colonizing so densely it seems a nuisance, particularly in the southeast, where its aggressive habit has earned it the names Hellvine and Devil's Shoestring.
The woody perennial vine can take over a yard in a single season in the warmest, wettest places, growing 30 and 40 feet tall and covering trees and fences faster than you say “Damn that invasive plant!” If you're not vigilant, trumpet vine can escape your yard and choke out other plants in the surrounding landscape. With adequate care and pruning, trumpet vines can be kept under control.
Yeah, I think it’s the same plant. I bought it (two plants) online about 11 years ago, planted it and it has grown to where it took over my back fence. One I planted by a tree next to the patio, but that one has gradually died off probably due to too much shade. I have tried planting the seeds but didn’t use stratification.
Thought I’d try cuttings this year, since the grapevine and blue sky vine cuttings worked pretty well. I’m no expert gardener, by any means, but I am also no novice. The seeds that drop from the vine have never grown new plants for some reason.
