Graves’ Blackberry: A Compact Native Shrub for Naturalistic Gardens
If you’re looking for a low-maintenance native shrub that won’t take over your garden, Graves’ blackberry (Rubus allegheniensis var. gravesii) might just be the perfect fit. This lesser-known variety of the Allegheny blackberry brings all the benefits of native plants while staying refreshingly compact – a trait that many gardeners will appreciate!
What Makes Graves’ Blackberry Special
Graves’ blackberry is a perennial shrub that belongs to the rose family, and it’s got some serious staying power. What sets this variety apart from its more aggressive relatives is its modest size. While many blackberry species can become garden bullies, spreading far and wide, this little gem typically stays under 1.5 feet tall and rarely exceeds 3 feet at maturity.
You might also encounter this plant listed under several botanical synonyms, including Rubus marilandicus, Rubus tumularis, Rubus uber, and Rubus virginianus – botanists sure love their naming conventions!
Where Does It Call Home?
This native beauty has quite an impressive range across eastern North America. You’ll find Graves’ blackberry naturally occurring from Nova Scotia down through the eastern United States, including Connecticut, Kentucky, Maine, Maryland, New Hampshire, New York, North Carolina, Ohio, Tennessee, Vermont, Virginia, West Virginia, and Wisconsin.
Why You Might Want to Plant It
Here are some compelling reasons to consider adding Graves’ blackberry to your landscape:
