Hi, I too am interested in growing some of these outdoors year round in zone 5. I am also interested in other bulbs that would over winter outside here. I have all of the common ones and just purchased several gingers, an agapanthus and have two of the Crinium Jumbo. What I am interested in is the more tropical bulbs, ones from Africa, etc. What have the rest of you in colder zones had success with? I do not mind mulching if need be. Thanks, Sheri
