Trumpet Vine
Campsis radicans
Trumpet vine is the single most attractive plant for ruby-throated hummingbirds in the eastern US — the flower's geometry, depth, and color saturation evolved specifically for hummingbird pollination over millions of years.
How to care for trumpet vine
Plant ONLY where you can mow ALL escape suckers — trumpet vine sends underground runners 50+ ft from the original plant and is nearly impossible to remove once established. The hummingbird draw is unmatched though.
