So I'm getting a Amaryllis Samba bulb from Royal Colors, which is great! However...they went ahead and shipped it, and I'm worried it's going to be a goner by the time it gets here :( Doesn't get here until most likely the 27th, and the area the package is residing now is 18 f.....How cold can these guys stand? I'm so worried it's going to be dead. They sent it even after I told them of the temperature dilemma. Does it have a chance?
