Gardeners' Notes:

I've only ever found one of these flowers growing wild in an abandoned farm field next to our property, at the end of June in 2003. I didn't mark where the flower was and have never been able to find it again. I don't know whether it's gone, or I'm just overlooking it (very easy to do in an overgrown field). For that one moment, at least, I was thrilled to discover such a rare beauty.
My wildflower book says that this flower's range should be Manitoba east to Newfoundland, south to Georgia, west to Texas, and north to Kansas, Iowa, and Minnesota.

This orchid is regularly encountered in most Newfoundland fens. The flowers are usually pale green but can be nearly white or somewhat yellowish-green. They are pollinated by moths. Not that showy and probably best enjoyed in the wild. This species may be endangered in some locations.
