I've had Meiracyllium trinasutum for more than 40-years, having bought it as Soph. cernua from Spencer Howard (Howard Spencer?) back in the 70s....so it is long-lived. It flowers abundantly every year, spring through fall, and is pretty much neglected over winter (only an occasional watering). Leaf tips seem to get quite reddish in higher light. I like the cinnamon scenting of the flowers.
