I finally figured out what this is (thank you, Internet!). I believe it's Bracted Spiderwort, ... The following is from the U.S. National Park Service website :

 

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.
