This month's featured plant is one of my favorite perennials. Epimedium is a adaptable, four season, shade loving, drought tolerant spreading perennial that makes a great bed edge or groundcover. Did I mention that it has almost no pest and disease problems, and that deer and rabbits leave it alone? And it has unique spring flowers. It deserves a spot in any landscape with shade, and it's a shame it isn't more widely known in Indiana.
In addition to having countless beneficial features, Epimedium also has more common names than I know of for any other plant, so I refer to it by its scientific name to avoid confusion. The uniquely shaped flowers have earned it the names Bishop's Hat and Fairy Wings. It was once believed to be a contraceptive, which earned it the name Barrenwort. One of its less common names is Horny Goat Weed, and I'll let you guess where that name came from. There are a handful of species and hybrids of Epimedium that are grown for landscape use with a range of varieties available, but all originate in Asia. Different varieties have different flower colors and sizes, but all varieties start off early in the spring with a fresh flush of pink and red tinged heart-shaped leaves that mature to a bright green that lasts all the way through the growing season and into the winter.
