Thanks for all the nice posts here all. A pleasure and privilege to share orchid pics with all here - and I totally enjoy seeing the beautiful orchid flowers that you all upload on Slippertalk, which makes one of the best orchid shows in the world (or ever!).
Good comment about the colour break OP! ------- some welcomed individuality there with that flower. Possibly just a natural occurrence ----- the other flower doesn't have that birthmark.
Know what you mean though! I look at orchids in this way - in that I read that many orchids out there may have viruses in them. And orchids/plants that survive indefinitely after getting particular viruses will be along the lines of 'natural selection'. The chance of all orchids getting wiped out by viruses on the planet is relatively small - maybe even zero chance.
This also brings up an interesting topic of studies (if any at all by researchers) done on birthmarks or patterns seen in orchid flowers that just developed naturally --- as in virus-unrelated patches/birthmarks.
At the moment - when I use google or some other search engine and look for 'natural blemishes orchid flowers' or 'color break in orchid flowers', there appear to be pretty much zero (no) discussions or information about natural virus unrelated patterns or variations that could potentially be observed by growers. Interesting situation.
This one was purchased from Rosella Orchid Nursery - aka 'RON'. It had much more bulbs than it currently has. I cut it in half last year, and gave the other half to a friend that was getting back into hobby orchid growing again.
