Orchid variants

[mike-c]

Saw these three orchids yesterday. The small purple one , I assume, is a Common Spotted Orchid, but how about the other two? The pink one presumably is going over, and changing colour in the process, but the white one had no - or very feint - markings and was much taller than the others.
All three were clustered together within about a metre of each other.

Hi Mike,
All three are Common Spotted Orchid. They come in all shades between deep pink/purple and pure white and the level of marking on the lip is also highly variable, from none in the albiflora variety to completely solid colour in the rare rhodochila variety.
Your white one still has some faint markings though so can't quite be classed as the white albiflora, but they are relatively common so keep looking.
