>Aren't most bulbs/corms/tubers water (as well a other things) >storage organs, and so technically succulent? Dear Tim, Off hand I'd think so without getting into technical discriminations especially since we/PBS tend to include a wide range of plants with storage organs - rhizome, thickened roots, tubers etc....and we often PUSH the limits by including all of a genus when only a few qualify. The thing with caudex forming plants is that many/ some? only show this enlarged storage stem (usually) if they are planted abnormally high and above their 'natural' soil level. I suppose that might include a true bulb growing with the majority exposed (Boweia for a recent example). So some bulbs are routinely included in succulent shows and some plants with water storage organs are planted to expose this feature in succulent shows, but there are surely exceptions and lots of limits. For example Leeks versus onions. Both in the same genus, the former neither succulent nor bulbous, the latter both (some might disagree). Others can add 2 cents worth. Best Jim W. -- Dr. James W.
