Ginda,
Eastern Huckleberry, Gaylussia baccata, is available Tripple Brook Farm
in Massachusetts www.tripplebroolfarm.com
My Black Huckleberry, Vaccinium ovatum, came from Burnt Ridge Nursery
www.burntridgenursery.com but it hasn't underwent a really cold Minnesota
Winter yet. Their catalog doesn't say zone 3 but I got it verbally. People
tell me that I should have bought Red Huckleberry (Vaccinium parvifolium);
one sent me some seed which I planted so we'll see. I'd have rather bought
Black Huckleberry from a Montana nursery; they openly claim zone 3 hardiness
but are provincial with their plants refusing to sell outside their home
State.
It was a west-coast huckleberry I tried to grow, helpfully provided
by a west-coast NAFEXer. I also bought some from Forest Farm.
Vaccinium Ovatum sounds right. Maybe the hardiness varies by where
the parent stock comes from? Maybe my shade is too dry? How wet is
your land? I've thought about trying east coast huckleberry, which I
know is hardy a couple climate zones north of me, but it doesn't
fruit much in the shade, and is hard to find and to transplant.
Maybe I should try Vaccinium Ovatum again. What was your source?
