This one seems more common than it used to be in cultivation, with pretty good reason. Really huge flower relative to plant size, up to 1½". The flowers last about a month. It's been flowering successively, but sadly by the time the new flower opens, the old one fades about a day later, so I haven't had a chance to take a photo with two flowers at once. This is the 4th flower of the season, and there's one more on the way. Bright light, intermediate temps, relatively moist, though drying out a bit between waterings.
