Windham County Blackberry: A Rare Native Gem Worth Knowing About
Meet the Windham County blackberry (Rubus flavinanus), a native North American shrub that’s so rare, you’ve probably never heard of it – and that’s exactly what makes it fascinating! This little-known member of the blackberry family is one of those quiet conservation stories that deserves more attention from native plant enthusiasts.
What Makes This Blackberry Special?
The Windham County blackberry is a perennial shrub that stays refreshingly compact, typically growing under 18 inches tall and never exceeding 3 feet at maturity. This low-growing habit sets it apart from its more boisterous blackberry cousins that can take over entire fence lines. You might also see it referenced by its botanical synonym, Rubus angustifoliatus.
Where Does It Call Home?
This native beauty has a surprisingly limited range for a North American plant. You’ll only find Windham County blackberry growing naturally in three states: Maryland, Vermont, and West Virginia. This restricted distribution is part of what makes it so special – and so rare.
The Rarity Factor: Why You Should Care
Here’s where things get serious for a moment. Rubus flavinanus carries a Global Conservation Status of S3?Q, which essentially means we’re not entirely sure how rare it is, but it’s definitely not common. This uncertainty speaks to how understudied this species remains, even among botanical experts.
What this means for gardeners: If you’re lucky enough to encounter this plant, treat it with respect. This isn’t a species you’ll find at your local garden center, nor should you dig it up from the wild.
Should You Grow Windham County Blackberry?
The honest answer? It’s complicated. While supporting rare native plants is admirable, the limited information available about this species makes it challenging to grow successfully. Here’s what we do know:
- It’s a true native to the eastern United States
- It maintains a compact, manageable size
- As a perennial, it should return year after year once established
- Being a Rubus species, it likely produces small berries (though specifics are unknown)
The Growing Challenge
Unfortunately, detailed growing information for Rubus flavinanus is scarce. We don’t have reliable data on its preferred soil conditions, sunlight requirements, hardiness zones, or care needs. This information gap is partly why the species remains so rare in cultivation.
If you’re determined to work with this species, you’ll need to:
- Source plants only from reputable native plant nurseries with proper documentation
- Never collect from wild populations
- Be prepared for some trial and error in growing conditions
- Consider it an experimental addition rather than a sure bet
Alternative Approaches
For most gardeners interested in native blackberries, consider these better-documented alternatives that provide similar benefits:
- Common blackberry (Rubus allegheniensis) – widely available and well-understood
- Red raspberry (Rubus idaeus) – native in northern regions with known growing requirements
- Wineberry alternatives that support local wildlife
The Bottom Line
Windham County blackberry represents the fascinating world of rare native plants that exist just beyond our everyday gardening experience. While it may not be practical for most home gardens due to its rarity and our limited understanding of its needs, knowing about species like this reminds us of the incredible diversity still waiting to be fully understood and appreciated.
If you live in Maryland, Vermont, or West Virginia and are passionate about rare plant conservation, consider supporting local botanical surveys or native plant societies that work to better understand and protect species like Rubus flavinanus. Sometimes the most important thing we can do for a rare plant is simply to know it exists.
