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.

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.

This is perhaps the best of many field guides covering this region. Featuring 446 excellent color photographs (located

1,200 species. The start of each family section includes line drawings of some of the species showing important
features. The text includes the usual description, bloom season, range, habitat and additionally includes information
such as medical uses and lore and how the species was named. This is the official field guide of the Tennessee
Native Plant Society.
