Unknown White Cattleya Hybrid - ideas on parentage?

[mjHuntingtonBeach]

This was my first orchid... about 30 years ago a college friend went to a meeting of the Long Beach orchid society and got this plant as prize, it was dying, she gave it to me and I have had it ever since. Was the only cattleya that bloomed regularly for me indoors, and then I found that when I kept it outdoors here in Southern California, it kept growing and blooming. Likely I will never know the name of this cultivar, but was wondering if anyone had ideas on the species that might have gone into this? C. labiata? C. percivaliana? Maybe L. purpurata? All I know is that it seems to be tolerant of temperatures here in So Cal, although it does seem to be happier and blooms more readily indoors, even in lower light levels.

Here are some blooms today, November 23, the plant was outdoors all year long except for the past three weeks or so.

As this hybrid is older than 30 years, it might be a Bow Bells or a cross with Bow Bells. Parentage might include the mossiae fma. wageneri, gaskelliana, trianae, even a white percivaliana - impossible to say. The shape with overlapping sepals/petals is great.

Beautiful classic white cattleya! In the 1940's & 50's white cattleyas were raised by the thousands for the corsage industry. Because of the demand for cut flower white orchids, breeders made lots of white crosses. So, with so many crosses, chances are you'll never be able to know what it is for sure. It's certainly a beautiful orchid though.
