This low growing plant is found only in the Central Basin of Tennessee where it often grows in great masses. It is one of the flowers that live in the shallow soil of the cedar glades where it relies on the wet weather of winter and early spring to complete its life cycle while there is enough moisture in the thin soil. I sometimes see some flowering in January. The small flowers are very fragrant and a large area of them can produce an almost overpowering perfume. The color variations are somewhat separated geographically though they can sometimes be found growing together. The white variety is found mostly south of Nashville and the yellow Nashville and north.

Similar Species: This plant is easly confused with the much rarer and somewhat smaller Necklace Gladecress, Leavenworthia torulosa.

One of the best general guides to wildflowers of the North Eastern and North Central United States. Newcomb's key is an excellent, simple method for identifying plants. Newcomb has drawings for almost every plant mentioned that are excellent aids to identifying the species. Though only the more common plants are covered this is often the first book I pick up when trying to identify a wildflower.
