@Felthry blackberry.
Grows all over the place into giant brambles as a nuisance plant in the PNW.
@starkatt they're good berries, yeah
we're partial to blueberries, personally. would love to try lingonberry sometime though. Never had it and it's supposedly really good.
(i mostly made this poll to surprise people with increasingly esoteric berries until finally reaching bananas, which are technically a berry but almost no one who isn't a botanist knows that. pumpkins and watermelons being berries is well known as a weird bit of trivia but for some reason bananas aren't usually mentioned)
