Well, an expedition to north Hampshire produced some startling results! We found some Fly Orchids in leaf. pictures are in the gallery 'Orchids in Winter"
Many books suggest that these plants are in 'winter-green' but we are of the opinion that this is not the norm. The plants that we did find were few and far between and more importantly those were all in a 'blanket' of sphagnum moss so we think that these are isolated examples growing in their own micro-climate.
Your comments/observations are welcome.
