Keep in mind there are at least two fruits called “huckleberry.” I’m referring to the one that grows wild in Cascadia.

There are various purple things in Vaccinium, and there’s something red down in the southeastern US in, IIRC, the Solanum family.

My experience has been that Vaccinium membranaceum is better than Vaccinium ovatum. Unfortunately, Vaccinium membranaceum likes to grow in places that are obnoxious to get to, and hasn’t been successfully domesticated.

Wikipedia lists four, not two:

Huckleberry is a name used in North America for several plants in the family Ericaceae, in two closely related genera: Vaccinium and Gaylussacia.

• Cyrilla racemiflora (known as “he-huckleberry” in the family of Cyrillaceae)
• Solanum scabrum, (known as “garden huckleberry” in the family Solanaceae)

EDIT: Apparently the Solanum huckleberry isn’t red. Oh, well.
