sour cherry, Prunus cerasus

Cherry pie! Cherry cheesecake! This may be one where I'd rather see the results than the beginning. But here's the beginning. Sour cherries started out in Europe and west Asia, but how could we not spread them around. Now they show off in AK, AR, CA, CO, CT, DE, GA, IA, ID, IL, IN, KS, KY, MA, MD, ME, MI, MO, MT, NC, NE, NH, NJ, NM, NY, OH, PA, RI, UT, VA, VT, WI, WV, BC, NB, NS, ON, PE, and QC.
