Compared to crabapples, yesterday's mess of pears are a pristine and orderly bunch. Siberian crabs are a common part of the mix. Back around 2009 I realized that information on escaped crabs was pretty skimpy, considering the number of them I had seen on my wild wanderings. So I went on a crab, and ultimately pear, collecting binge. Siberian crabapple was probably the most common. But they all hybridize so freely it's impossible to know just what you have with any individual. All the specimens got labelled before I turned them in to the University of Michigan Herbarium. They like to know where to file them. But I can imagine that batch getting repeatedly relabeled far into the future. Or I can imagine that no one will really care! This one mostly seemed like Siberian, which has been reported from CT, IL, KY, MA, ME, MI, MN, MO, NC, NH, NJ, NY, OH, PA, RI, SC, TN, VA, WA, WI, WV, WY, NB, NF, NS, ON, QC, certainly other states, particularly in the northeast.
