What month did you see the orchid? If it was flowering in January, February, November or December, then it is most unlikely to be an orchid. You can see orchid leaf rosettes like the ones in the picture below quite easily in these months though. These are Ophrys spp and Lizard Orchid leaf rosettes photographed in February, growing through a patch of Wild Thyme on the nature strip near the library in Preuilly. Don't confuse orchid leaf rosettes with those of Ribwort Plantain Plantago lanceolata.
|The smaller orchids, early in the season, can be very difficult to spot when they are just leaf rosettes. There are at least 5 Ophrys spp leaf rosettes in the photo above, taken in our vegetable garden. Can you spot them?|
|Just in case you couldn't see them, here they are marked by red ovals.|
Use the following series of photographs to get an idea of what your orchid might be, based on when you saw it and the colour. This is just a selection of the most likely orchids you might see. Many of these can be easily seen on rural roadsides. A complete list of all the orchids you can see in les 3 départements (Indre, Indre et Loire and Vienne) can be seen here.
Orchids can be confused with Broomrapes Orobanche spp by beginners, but it won't take you long to learn the difference.
