The white ones come in a little earlier but don't have enough of those. Not sure where they came from but they are awesome berries. Started with just one volunteer briar and I've been spreading them. Got a fair little bit started now but not enough to make anything with yet. Enough to eat though. Best I can find out it's bound to be these: https://en.m.wikipedia.org/wiki/White_blackberry Not sure exactly like I said they just showed up here so I don't know but they look identical to those and can't find anything else even similar. Really pretty white berry
