Funny thing about this particular orchid species: It blooms only after a few, rather specific meteorological conditions have been met, and then for only a few hours that day. Read more at Jim Fowler's blog.
The leaves are unusual for orchids, being about 1/2-inch long, heart-shaped but clasping, and a handful scattered along the stem. Learn more at Vascular Plants of North Carolina.
