Sam tells a tale about a trip to Yellowstone. Sam, "What's that yellow flower?" Park ranger, "It's a DYC." That turns out to be a damned yellow composite. A fun answer to a very big question. There are an awful lot of DYCs. And more than a few look an awful lot alike. The sunflower style alone presents us with an almost bewildering array of species. Telling them apart is wonderful fun. There are Heleniums, and Helianthellas, and Helianthus, and Heliomeris, and Heliopsis, and so on. But not Helianthemum. Patience and a good book or website (Michigan Flora!) will do the job. Or just settle for DYCs. That's fun too. Ox-eyes are one of the more common DYCs that aren't sunflowers. They grow in AL, AR, CO, CT, DE, FL, GA, IA, IL, IN, KS, KY, LA, MA, MD, ME, MI, MN, MO, MS, NC, ND, NE, NJ, NM, NH, OH, OK, PA, RI, SC, SD, TN, TX, VA, VT, WA, WI, WV, MB, NB, NF, ON, QC, and SK.
