Reader brought up the topic. I've seen patches of what we called Huckleberries growing on field edges in New England. Never tried to eat one and never heard of people picking them. Next time I see some, I'll try them before the grouse get them.
There are several plants around the country which people term Huckleberries.
At some point, Huckleberry became a term of affection.
