Thank you, Maggi. I am in New Jersey, near the Atlantic Coast, Zone 6/7. I found that Pleione do not survive outdoors here, at least under my care. I do not have a glass house, but there is a completely glassed-in, but unheated, porch. This would provide protection from the elements, although temperatures are only slightly moderated.
And thank you, Lars. I am awaiting a reply from the source you mention, he is preparing a list of available Pleione; just sent hime a reminder. That is an excellent website you mention.
Modified to ask: can Pleione be grown successfully under fluorescent lights?
