Title: Growing Crossvine on a Wrought Iron Fence in Austin
Answered by: Mike Tomme

QUESTION:

I would like to plant crossvine along a wrought iron fence. Will it damage the fence or the stucco posts?

ANSWER:

I'm pretty sure your wrought iron fence is safe, but I'd keep a close eye on those stucco posts. Bignonia capreolata (Crossvine) is usually less agressive than its look-alike relative Campsis radicans (Trumpet creeper), but both vines put out out rootlets that will exploit any small cracks they find. These can be quite destructive, particularly to wooden structurres like houses or fences.

If you maintain your posts to be sure cracks don't develop and keep the crossvine trimmed back away from the posts, you should be okay.

As an alternative to crossvine or trumpet creeper, Mr. Smarty Plants usually recommends Parthenocissus quinquefolia (Virginia creeper). This vine puts out tendrils that attach to the surface of the structure and cause little or no damnage. Of course, what you give up is the showy spring and summer flowers. You do get colorful fall foliage though.
