Hairy Spiderwort (Tradescantia hirsuticaulis)

Tradescantia hirsuticaulis is known by the common names Hairy Spiderwort or Hairystem Spiderwort. Blooms are usually purple or rose-pink; some blooms may be white. We found plants in various stages of blooming along the trail before we crossed the creek. At Rock and Shoals Outcrop Natural Area, we found them growing thickly on the hillside by the trail leading up to the stone outcrop in mid-April. We saw both purple and rose-pink blooms; most were purple.

Although purple blooms predominated at Rock and Shoals Outcrop Natural Area, we found rose-pink blooms predominating in a lawn near the Broad River Wildlife Management Area.

Tradescantia hirsuticaulis
is native to the United States; it is found in dry woods and rocky outcrops in Oklahoma, Arkansas, Tennessee, North and South Carolina, Georgia, Alabama, and Mississippi.

Spiderwort is one of the few showy, native spring wildflowers to be found here on Jekyll, and I love it for that reason. I miss the April wildflower explosion in my home state of Ohio!

The spiderworts are really showy when they turn up in masses like they did at 'Rock and Shoals' and the field we saw in Wilkes County.
Glad you're getting to enjoy them on Jekyll Island. Does the salt air limit the variety of wildflowers on the island?
