Dear All, I've always thought these were orchids, but they have so stubbornly refused to bloom that I need to double-check. I've had them for 2-3 years, they are planted in bark + peat moss, they have air roots, they are allowed to dry off between waterings, they have grown very lush by comparison to when I got them, and they _just_don't_bloom_. Are they orchids? What kind? (I have that catch-22 that I don't know which ones they are, so I can't look up good care advice.) Any tips on getting them to bloom? Thanks a lot!
