If one knows where to look, within 100 miles of downtown Chicago one could see up to 17 species if you took a number of trips over the year. Walking distance from my home is Illinois Beach State Park, on Lake Michigan, have seen Spiranthes magnicomporum, Platanthera psychodes, Platanthera leucophaea which is in bloom right now, Calopogon puchellus, and a few orchids with mostly green flowers, that I don't bother checking up on. Cyp candidum population just off a main thoroughfare in an industrial park in a near north suburb. They are all around, just not easy to find. Platanthera leucophaea photo from cell phone, so humid that day, 7/8/2013 that the lens kept fogging up. This is great orchid watching, I did not have to get out of the car! :rollhappy: I just rolled down the window and took the picture. It was growing in one of the north sections of IL Beach SP, in the dogwood shrubs right next to the road. Now that is how I like to hunt for orchids, staying seated in the air conditioned car.
