Cattleya Bob Betts (1950) was Bow Bells crossed back to mossiae, so it is 69% mossiae, 19% gaskelliana, and 12% trianae. There are 73 AOS awards for Bob Betts with the most recent one for flower quality in 1974. I think this is the most awarded white Cattleya. 'White Lightening' seems to be the dominant cultivar available in recent years (and what I have), but it is not awarded and I don't think we know where/when it originated. It must have been mericloned to be so available. My fantasy is that there are amazing other cultivars of Bob Betts sequestered in private collections, almost like works of art. Chadwick's do have 'Tacoma' AM/AOS available for $75 so I suspect this might have come from a mericloned line, but maybe not. I would like to know about other cultivars of Bow Bells or Bob Betts that our little group of forum members who love Cattleyas might have or have seen. My Bow Bells is 'July', which was not awarded. I know a non-awarded plant can be great, but some of the pictures I have seen of old awarded Bow Bells and Bob Betts look better than anything I have been able to get in about 4 blooming of each of my plants.
White Cattleyas.. such a fun corner of the orchid world, riddled with rich history and desire.. I'm completely addicted to these.. I've watched this presentation countless times (). I purchased a small flask of Cattleya Bob Betts ‘The Virgin' FCC/AOS x Cattleya Bob Betts ‘Conqueror’ FCC/AOS. a few years back from Marni Turkel. She has an ebay storefront 'Mostlyspecies'.. linked from her website.. (Orchid Plant Sales). Some really cool plants rotate on her listing. I'm looking forward to blooming one of these out in the coming years. 'there are amazing other cultivars of Bob Betts sequestered in private collections' YES, I subscribe to this point of view.
