This is my only Tuberolabium but I think I'm hooked. This is a FBS. The blooms are only about 5mm wide but I do not know if the bloom size will increase as the plant ages (IOSPE says bloom size is 1/2 inch). Fragrance is like coconut sunscreen much like Max. tenuifolia. Grown bright, intermediate, daily summer water. Mid-day temps often exceed 90 F. but it seems happy.
