LousewortLousewort - what a lousy name for such a fascinating plant! This mid-spring wildflower has some very unusual features, as well as a sense of whimsy about it. It is fairly common, growing along roadsides and trail margins at low to mid-elevations, where it is likely to get a fair amount of sun. The leaves may appear very early on, and they're fairly easy to identify - long and narrow with deeply-cleft teeth, emerging in a tightly-packed whorl from a sunny patch of ground. The early  leaves are usually a deep purple color, and they are covered in long downy hairs. By early to mid-May, the leaves have turned to green and are about 6" long, growing mostly in a basal rosette but a few small leaves may appear alternately along the flower stalk. The flowers appear in a round "head" at the end of a single stalk, about 6" high or a little taller than the leaves. The flower head formation is unusual and attention-getting because the individual flowers bloom in a spiral-shaped formation around the outside of the flower head, in a geometric pattern somewhat like a pine cone. The individual flowers average about 1/2" long , appear hooded at the top, and contain a variety of colors ranging from pale yellow through reddish-purple to reddish-brown. Lousewort is a member of the Scrophulariaceae family - a very large family that includes  Mullein, Turtlehead, Beardtongues, and many others, but its hooded or capped appearance might fool you into thinking it's a mint or scullcap. Louseworts will fade away by mid-June, though you might continue to see a dried-up leaf or two through the summer.
A note on the nomenclature (naming conventions) on this site: Scientific names and classifications are constantly being argued and changed, and it drives me nuts. Although I use many different sources for knowledge, for naming consistency  I  use the  "Manual of the Vascular Flora of the Carolinas" by Radford, Ahles and Bell, 1968 edition. This book is a well-established authority for the plants of our region and I've been using it for years. If for some reason I must use a different source for a particular plant, I will make note of it within the descriptive text. Don't like it? Tough!
