Growing Vines on Trees: Why Not?

Climbing hydrangea (Hydrangea petiolaris) is an expert tree-climber!

Tired of looking at naked tree trunks in your wooded garden? Why not spice them up with the attractive foliage and flowers of a climbing plant? Many gardeners seem to think that vines can only be grown on a trellis of some sort, but in the wild, almost all grow up trees or tall shrubs. And there’s no reason you can’t repeat this oh so very natural way of growing in your garden!

Climbing plants with aerial roots or suckers, such as Virginia creeper, Boston ivy, English ivy and climbing hydrangea, are the most obvious choices. They’re designed to latch onto any kind of surface, including tree trunks, and will therefore climb all on their own. You just have to plant them at the foot of a tree and up they go. A snap!

Twining vines take a little more thought. Some have twining stems that form large spirals and can therefore wrap around all but the thickest trunks. Therefore they will almost always climb on their own. In this group are American bittersweet (Celastrus scandens) and Dutchman’s pipe (Aristolochia macrophylla).

Some aren’t quite so “encompassing”. Scarlet runner bean and morning glory will wrap their stems around a moderate size branch, but not a thick trunk. Attach a trellis, netting, or cord to the trunk and let them grow on that.

Clematis ‘Perle d’Azur’ needs netting or cords to “get a grip” on a trunk.

Clematis is an even weaker climber: it has twining petioles (leaf stems) and they can only manage to cling to a very thin support. Even some trellises are too thick for them! Cords or netting are good choices for directing clematis up a trunk. Of course, once they reach the first branches, they’re usually able to climb on their own.

Finally, climbing roses are the most hopeless climbers of all. Even a trellis is of little use! Simply tie them to the trunk to launch them in the right direction. Once they’ve reached the tree’s lower branches, though, they’re fine on their own: they readily mingle with branches, using their thorns as hooks to hoist themselves further up.

There you go: lots of ideas for bringing those dull trunks to life… and giving your garden a lusher, junglelike appearance.

    Have you ever seen or heard of growing a vine called Petrea Volubilis up s tree trunk? It’s s woody vine and does not have arias roots.

    • Yes, it will clamber up trees by twining. As such, it may need to be attached to the trunk until it reaches branches thin enough to twine around.
