I will take the darker pink and the bi-color!
I am for the red - but can't grow them.
That's a stunning group. Congratulations. I can't keep them alive.
Very nicely done. All Tom Perlite's?
Very nice selection, and well grown.
I don't see any semi alba in there, still have some very nice ones.
Nice collection, Daniel!
Thanks for the pictures, very impressive.
Thank you all.
Wish some of the better ones I have were looking better to put in.
Mike, the semi alba I have is a recent division, no flowers yet. If there were, I'd abort them for a healthier plant. Can you call a pink/white bicolor semi alba?
Chad, pretty much all Perlite breeding or something to do with Golden Gate Orchids.
You may call it if you wish so, especially if you send me one of those pink/white bicolor... Just make sure it is a good one though.
I just flowered a surprise one , it's a light rose over white. I thought the buds were blasting because it had that look of discolor to them. I'll take a couple pics tomorrow. I have another dark pink/white with a (x tannii) fruit on it.
Sam and Kelly - I'm with you on the difficulty under my conditions, but someone in my OS has been successful by setting up small "orchid tanks" in his basement, providing no extra heat, and lighting them with my LEDs to avoid more heat.
Something to consider - I may give that a try myself.
Tks Ray - my problem (have many ) is to get them cooler...
The one that I just am seeing for the first bloom is the smaller lighter one.
Interesting pink-white clones...........For bicolor, I prefer clean markings, so I like your red-yellow bicolor better.
How would a red over white be accomplished? Could a very weak base be introduced to achieve a lower pH?
it probably couldn't. pink/purple based flowrs contain anthocyanins (violet purple pigments), no yellow pigments.
red based flowers contain both anthocyanins and yellow pigments, so the purple appears red. But the flower parts where there are no anthocyanins can't be white, as the yellow pigment will be there. I've seen a picture of a cuthbertsonii clone combining pale yellow tips with purplish red flower base. This is not common, and probably contains only a fraction of the "normal" yellow pigment dose.
