How to plant banana lilies

I've just bought today what was labeled as "banana lilies". No one I asked
was sure how I plant the lilies - bananas pointing down or up!? When I try
to find info online, I can't find the same banana lily that I have. I only
find the all green banana lilies; mine have some reddish tinged "bananas"
and the leaves are edged in a pretty burgundy color. Here are a couple
photos:

Now, would anyone be able to tell me how I plant these? Or are they like
the all-green banana lily, and I don't plant them at all? Thanks for your
info!
