Dell, Eustephia jujuyensis (I can't throw any light on the validity of the name) makes a big bulb with a long neck. I also dry mine off in winter but it will only flower if it gets a prolonged cold spell. It will take temperatures all the way down to freezing but I keep mine just frost-free and it flowers regularly in spring. Phaedranassa dubia may be a little more tender and will flower any time of year following an 8 week enforced dry spell, otherwise it will remain evergreen. After flowering, it must be given a minimum 4-month growing period and thus it will flower twice a year. It is a very handsome plant and ideal for bringing into flower for special occasions. I grow both in very lean, gritty compost with occasional feeds of weak (25% normal strength) high-potash liquid fertilizer. I have trouble flowering Eucrosia bicolor. Good luck.
