Here is some interesting information from the University of Georgia on what we can use as perrenials in zones 7b-8b. Not bad! Some nice images of Brian's original Alocasia hybrid in landscape as well!

For those of us NOT in zones 9-10
I have read this article very interesting. I have enjoyed reading their compliments on my hybrid. I am glad to see it getting a bit more popular.
I have been to the UG Griffin Trial Garden, which is awesome! If I ever go again, I need to pay closer attention to their use of tropicals. Thanks for the link!
