Mocassin flower is also often called pink lady-slipper. Of our dozen lady-slippers, it may be the most encountered by the most people. It grows in drier ground than our other common species, and over a wide territory. But it also has the most exacting requirements. If soil acidity changes to above pH 5, goodbye. Other habitat changes can also result in a quick exit. As a result, this has been a protected plant, along with its orchid kin, in many places for a long time. Moccasin flower grows in AL, CT, DE, GA(U), IL(E), IN, KY, MA, MD, ME, MI, MN, NC, NH, NJ, NY(V), OH, PA, RI, SC, TN(E), VA, VT, WI, WV, AB, MB, NB, NF, NS, NT, ON, PE, QC, and SK.
