Orchid changing colour. My Lovely Orchid white with purple has just produced a pale yellow flower?

The orchid is about 4 years old, has lived in the same place, most of this time, has produced up to 33 blooms most years. Is it dying ? Or changing back to it's wild state.

I don't know much about orchids, but


a lot of plants have pigments that are


pH sensitive in their color. Hydrangeas


for example. Maybe orchids are similar.


You might want to check the pH of the


medium that you are growing it in


and maybe do some research on the


net to see if orchids can be that way.


I suppose it could also be other things


in the growth medium that may have


changed.
Reply:it could be that someone living nearby, has another variety of orchid and, it has cross pollinated.
