Climbing False Buckwheat: A Lesser-Known Climbing Perennial
If you’re looking for a climbing plant that’s a bit off the beaten path, you might have stumbled across climbing false buckwheat (Polygonum scandens var. dumetorum). This perennial climber is one of those plants that taxonomists love to shuffle around—it’s got more scientific aliases than a secret agent, including Fallopia dumetorum and Polygonum dumetorum.
What Exactly Is Climbing False Buckwheat?
Climbing false buckwheat is what botanists call a forb herb—basically, it’s a soft-stemmed plant without woody tissue that comes back year after year. Think of it as the opposite of a shrub or tree. Despite its climbing nature, it maintains that herbaceous character throughout its life.
Where Does It Call Home?
Here’s where things get interesting from a gardening perspective. This plant is native to Canada but has naturalized across a good chunk of the eastern and central United States. You’ll find it growing wild in states from Alabama up to Minnesota, and from Kansas over to Pennsylvania and beyond.
The Native Plant Dilemma
Since climbing false buckwheat isn’t native to most of the U.S. where it now grows, you might wonder whether it belongs in your garden. The good news is that it’s not currently listed as invasive or noxious, so it’s not causing major ecological headaches. However, if you’re passionate about supporting local ecosystems with truly native plants, you might want to consider native alternatives first.
Growing Conditions and Care
One thing we do know about climbing false buckwheat is its relationship with moisture. Across most regions, it’s classified as facultative upland, meaning it usually prefers drier ground but can tolerate some wetness. In the Midwest and Northeast, it’s even more flexible, happily growing in both wet and dry conditions.
Unfortunately, specific growing requirements, mature size, and care instructions for this particular variety are not well-documented in readily available sources. This might be partly due to taxonomic confusion—many references have shifted to using updated scientific names or lump this variety in with broader species descriptions.
Should You Plant It?
Here’s the honest truth: climbing false buckwheat falls into gardening’s gray zone. It’s not a troublemaker, but it’s also not a native darling. If you’re drawn to less common climbing plants and don’t mind a bit of mystery in your garden, it could be an interesting addition.
However, if you’re specifically looking to support local pollinators and wildlife, you might get more bang for your buck with a native climbing plant suited to your region. Consider these alternatives:
- Wild grape (Vitis species)
- Virginia creeper (Parthenocissus quinquefolia)
- American pipe vine (Aristolochia macrophylla)
- Native honeysuckles (Lonicera species)
The Bottom Line
Climbing false buckwheat is one of those plants that’s more of a botanical curiosity than a garden staple. If you’re a collector of unusual species or happen to come across it in the wild, it’s worth appreciating. But for most gardeners, especially those focused on native plant gardening, there are probably better climbing options that will provide more documented benefits to your local ecosystem.
Sometimes the most honest gardening advice is admitting when a plant is more interesting in theory than in practice—and climbing false buckwheat might just be one of those plants.
