There are about 500 species of Hypericum. Most get to be St. John's-worts. Apparently to belong to that club, you have to know how to grow leaves. So this one gets to be grass. Those little pointed bits on the stems are all the leaf this species produces. They're only up to three millimeters long. Of course, the name may also have something to do with the citrus aroma one gets if you crush the plant. The Cherokee use these plants to treat a variety of ailments, apparently to no avail. Orange-grass grows in dry open soil in AL, AR, CT, DE, FL, GA, IA(E), IL, IN, KY, LA, MA, MD, ME, MI(SC), MN, MO, MS, NC, NH, NJ, NY, OH, OK, PA, RI, SC, TN, TX, VA, VT, WI, WV, NS, and ON.
