Bracted Spiderwort, Common Spiderwort - Tradescantia bracteata
 

The flowers of the Bracted Spiderwort can vary from pale pink to deep purple or blue.  The color variation may be from the acidity or alkalinity of the soil or genetic variations in the plant.

Spiderworts are named because of weblike strands of mucilage made when a leaf or stem is broken.

Natural Entrance of Wind Cave  

Did You Know?
Winds caused by changes in barometric pressure are what give Wind Cave its name. These winds have been measured at the cave's walk-in entrance at over 70 mph. The winds at the natural entrance of the cave attracted the attention of Native Americans and early settlers.
