Orchid

One of my indoor orchids.
It is flowering well, and displays the orchid structures rather well.
It has unusual blotched petals, and I wonder if this is caused by a virus like the ones that cause striped petals in tulips?
I am lucky with my orchids now, they seem to repeat flower well and I think this is due to the even temperature that the AGA provides.
If you have difficulty with your orchids, I recommend getting one installed!
