You have to start them from root/rhizome divisions (rather like iris). The white butterfly one's good, you just have to overwinter them. I'm not sure what you're calling Blue Hawaiian ginger. If it's the Blue Ginger that's not a ginger but related to plants called wandering jew. For me even here in Florida, it's not all that easy to grow. At least it doesn't like 'sulfur water', which usually contains salt. Look around in oriental stores for 'ginger root'. I found a mostly evergreen one Alpinia calcerata in Orlando. The regular spice gingers have to just about stay dry all winter. I've lost several from not keeping them on their sides when they lose their leaves.(you won't know what you've got until you plant them)
