Dewberries are one of the tangle of variations on the blackberry theme. Rather than grow with higher arching canes, these sprawl along the ground. They're rarely more than a foot high. The flowers are often a little larger than other blackberries. Like blackberries, you're never too sure what you're getting when you pop a dewberry in. It may be delightfully sweet and tasty, or it might be bitter. Although in my experience, these are more often sweet than their taller relations. Northern dewberry is said to grow in AL, AR, DE, FL, GA, IA, IL, IN(E), KS, KY, LA, MA, MD, ME, MI, MN, MO, MS, NC, NH, NJ, NY, OH, OK, PA, RI, SC, TN, TX, VA, VT, WI, WV, NB, NS, ON, and QC(L). But with all the hybrids and variations, it's difficult to tell just what grows where with the blackberry complex. Lenawee Co MI, 5/27/18.
