Mohican Trail Dewberry: A Rare Rhode Island Native Worth Knowing About
Meet the Mohican Trail dewberry (Rubus maniseesensis), one of Rhode Island’s most mysterious native plants. This little-known member of the raspberry and blackberry family is so rare that most gardeners have never heard of it – and for good reason. With a conservation status that’s literally undefined and a distribution limited to just one state, this perennial shrub is more of a botanical treasure than a typical garden plant.
What Makes This Dewberry Special
The Mohican Trail dewberry is a low-growing native shrub that stays remarkably compact, typically reaching less than 1.5 feet tall and never exceeding 3 feet at maturity. As a member of the Rubus genus, it’s related to more familiar plants like raspberries, blackberries, and other dewberries, but this particular species has carved out its own very specific niche in the Rhode Island landscape.
Where You’ll Find It (Spoiler: Probably Nowhere)
Here’s where things get interesting – and a bit concerning. Rubus maniseesensis is found exclusively in Rhode Island, making it what botanists call an endemic species. Its Global Conservation Status is listed as SUSHQ, which essentially means we’re not quite sure what’s going on with this plant. That’s scientific speak for this species needs more study.
Should You Plant Mohican Trail Dewberry?
Here’s the thing about extremely rare plants: just because you can do something doesn’t always mean you should. Given the undefined conservation status and extremely limited natural range of this dewberry, most home gardeners should probably admire it from afar rather than trying to add it to their landscapes.
If you’re absolutely determined to grow this rare native, here are the critical considerations:
- Source responsibly: Never collect plants from the wild. Only purchase from reputable native plant nurseries that can verify their plants were propagated, not wild-collected.
- Know your purpose: Are you a conservation gardener working on habitat restoration? A botanical collector with proper permits? Make sure your reasons align with conservation goals.
- Understand the commitment: Growing rare natives often means you’re participating in conservation efforts, not just decorating your yard.
Growing Conditions and Care
Unfortunately, detailed growing information for Rubus maniseesensis is scarce – another indication of just how rare this plant is. However, as a Rhode Island native and member of the Rubus family, we can make some educated guesses about its preferences:
- Likely prefers well-draining soil similar to other dewberries
- Probably tolerates a range of light conditions from partial shade to full sun
- May benefit from slightly acidic soil conditions typical of New England
- As a low-growing shrub, it might work well as groundcover in naturalized areas
Better Alternatives for Most Gardeners
Unless you’re specifically working on conservation projects in Rhode Island, consider these more readily available native Rubus species that offer similar benefits:
- Northern dewberry (Rubus flagellaris): A widespread native dewberry with similar growth habits
- Common blackberry (Rubus allegheniensis): Taller but excellent for wildlife
- Red raspberry (Rubus idaeus): Native variety that provides food for both humans and wildlife
The Bottom Line
The Mohican Trail dewberry represents one of those fascinating botanical mysteries that make native plant enthusiasts’ hearts skip a beat. While it’s tempting to want to grow every rare native we discover, sometimes the most conservation-minded approach is to support research and habitat protection rather than cultivation.
If you’re in Rhode Island and passionate about native plants, consider supporting local botanical surveys and conservation organizations that work to understand and protect rare species like this one. Sometimes the best way to garden with native plants is to help ensure they have wild places to call home.
