Calopogon tuberosus (Common grass-pink orchid) white form

There is something blooming in my bog garden now that the pitcher plants have finished blooming. This orchid species is one that is usually seen as having magenta/pink flowers. However, occasionally there is a white one in the bunch. My original plant came from a roadside in North Carolina, near the Atlantic coast. Over the years, it has multiplied, and now it provides a bit of contrast with the dark red and yellow pitchers of my Sarracenia plants...
