It is a general remark......most are used inside, but southern Florida, around the Gulf Coast, Souther California and Hawaii they can also be grown outdoors. If we would include all the possibilities that gardeners can do with their bulbs, we would have to supply a book to list all the variences and most people would not read it. Studies have shown that people only read the BANG, BANG, BANG on a card or box and then give up.
So you are one of the lucky ones that can have the inside out.........most have the outside in.
