Dear Friends, Aaron did post an interesting comment about the plant to flower ratio of C. bulbsipermum. Yes there is a lot of plant there, but each plant puts up multiple flowering stalks over an extended period of time. And with a limited "Crinum Palette" in a colder climate, it is well worth the space it takes for my garden. More intriguing are his comments on C. campanulatum - On Jul 7, 2013, at 7:54 AM, aaron floden wrote: > ,,,,," maybe campanulatum should be thrown in to the mix as well? This only flowers for me if kept submerged year round in my bog garden, freezes and all. It was hardy in the ground, but never flowered without the excess water. It also has the benefit of flowering in late April to early May. " I never would have thought this is reasonably hardy species here and the wiki adds to the confusion about water or no water http://pacificbulbsociety.org/pbswiki/index.php/… Aaron, by 'submerged' do you mean a pot sitting in an inch of water or with the base and bulb completely covered in water? or something lese ? How low was your winter minimum when this survived icing over? Perhaps the "Crinum Palette' is bigger than I thought. I am confident growing any 'xpowellii', C. bulbispermum and hybrids, but suddenly there are more possibilities: C. variable C. variabale x bulbispermum C. x herbertii C. campanulatum Any one else grow other Crinum species in Zone5 or 6 or colder? I better start digging to accommodate all these new possibilities. Best to all Jim W.
