Trumpet vine inspires a strong reaction in most people; we either love or hate this plant, and it's a rare person who can claim they are neutral on the subject.
On the plus side, Campsis radicans is native to the U.S. and it flowers in hues of orange, red and yellow which are attractive to hummingbirds (and wasps and bees.) It clambers over fences, sturdy trellises and anything else it finds to climb on, quickly forming a lush screen of flowers and foliage all season.
Avoid planting Campsis radicans near a house or any other building, as it is an aggressive grower and climber, and will damage siding and shingles. It is more vigorous in mild climates where its growing season is longer.
In a thoughtfully-chosen spot, a trumpet vine can be a beautiful addition to the garden and provide nectar to attract hummingbirds. Just don't plant it where you'll have to wage a constant battle to keep it under control.
