Trumpet Vine
Campsis radicans
A native vine that covers fences and arbors in orange-red trumpets all summer, a hummingbird magnet that grows fast in almost any soil and shrugs off heat and drought. The trick is restraint: it suckers and self-seeds into thickets, so plant it where you can mow around it, on a sturdy support.

Place a row in your own yard and VeraScape spaces them at their mature width, so you can see whether they’ll crowd the walk.
