Botanical illustration of Trumpet Vine
Vine · Campsis radicans

A native hummingbird magnet that covers a fence or arbor in orange trumpets all summer — but know what you're planting: it's aggressive, clinging hard enough to pull down gutters, suckering from the roots, and self-sowing. Give it a strong freestanding structure far from the house, cut it back hard yearly, and enjoy the hummingbird show. 'Madame Galen' is a more restrained hybrid.

Questions

Trumpet Vine questions, answered straight.

Is trumpet vine safe for kids and pets?

Trumpet Vine is commonly eaten and isn't considered toxic, but "commonly eaten" isn't a guarantee for any particular person or animal — allergies, quantity, and which part you eat all matter. One caveat on this one: Foliage/sap can irritate skin (some people. Never eat a plant you haven't positively identified, and check with a vet before letting pets or livestock graze anything new.
