So Kim, is there a true semi-alba color form of walkeriana?
I am in no position to answer 100% yes or no to that question.
However, Gold Country Orchids (Alan Koch) is selling semi-albas, which I believe are at least in part based on Japanese breeding stock. I have a couple, which I have grown from fairly small seedlings; the largest is nearing BS now.
I have a high level of confidence in Alan, so I am leaning towards a yes.
