longleaf spiderwort, Tradescantia roseolens
Longleaf spiderwort is another botanical Geiger counter. When gamma rays are present the centers and filaments of the flowers can turn pink. No more radon tests, just plant spiderworts! Longleaf spiderwort grows in AL, FL, GA, and SC. Martin Co FL, 1/28/15.

Hi Denise
Just thinking it's almost time to come look for Platanthera flava. Bob
Hi Bob:
I found it on Eber Rd, about 1.5 mi S. of Kitty Todd Preserve 1/4 mi from Metroparks land. I’m guessing it came in on the RR. (NwOhio)
Apparently so, but not on all plants. The brown only shows a little in this image.
Regarding umber pussytoes, one reference calls it brown-brackted pussytoes. Are it's bracts browner than other pussytoes?
