Trumpet vine (Campsis radicans), also affectionately (or notoriously) known as the trumpet creeper, hellvine, or cow-itch vine, is a vigorous, fast-growing woody vine famous for its dazzling, tubular summer blooms and extreme durability.
Here are some fascinating and fun facts about this powerhouse plant:
Nature’s Hummingbird Magnet
- Prime Pollinator: The bright, tubular flowers are perfectly shaped for ruby-throated hummingbirds. The vine’s natural growing range almost perfectly matches that of these tiny birds!
- A Buffet for Ants: The plant trades food for protection! It features specialized glands (extrafloral nectaries) that secrete sweet, sugary nectar to attract ants. In return, the ants viciously attack any pests that try to eat the plant.
The Climber & The “Hellvine”
- Natural Spiderman: Trumpet vine clings to brick, wood, and rock using small, aerial rootlets (like suction cups) rather than tendrils.
- Aggressive Growth: Capable of reaching up to 40 feet in length, it can rapidly cover a trellis, but it is notorious for being aggressive. It earns its nicknames “Hellvine” and “Devil’s Shoestring” because its underground runners pop up everywhere, making it tough to eradicate once established.
