Another nice evening, so we called in at New Buckenham Common NWT to have a look at the Green-winged Orchids. After a bit of a wander I found around fifty flowering spikes close together, and proceeded to take some photographs, several of which were actually in focus! Several plants had paler white & purple flowers, but I didn't see any of the 'alba' variety that are all white with just the green streaks on the wings.
Incidentally, over the summer I am going to be looking for Green-flowered Helleborines, which apparently used to occur along the river valleys near Norwich. If anyone knows roughly where they occur(ed) then I would be very grateful for an email or message (probably best not to use the blog comments). Cheers.
