Tuber? Technically they are swollen stems.SurWrathful said:Keep it somewhere cool and dry. You don't want the bulbs to rot in too much humidity. Man, what is that term that describes bulb-like roots? Not rhizome, but what one would call scientifically a bulb much like Aponogeton spp. Same term applies to Gladiolus. But yeah, you wanna keep this bulb-like structure(><) in a place that is cool and dry.
