bristly blackberry, Rubus setosus

With blackberries, you start to feel that when you've seen one, you've seen them all. They're such a confusion with no end of variation, all mixed together. You could call them all the same thing, or you can have a thousand versions. Then there was this! Ever seen a pink blackberry flower? I don't think I had. Not only were some pink, but some had six petals. The pink seemed to be on the backs of petals, particularly in bud, and then becoming more visible as flowers began to fade. This one was just beginning to fade. I admit the color is very faint, but it was fun to see. Depending on how you delimit the species, bristly blackberries grow in CT, IL, IN, MA, MD, ME, MI, MN, NH, NJ, NY, OH, PA, RI, VT, WI, WV, NB, NS, ON, PE, and QC.
