Very cool. I figure the only thing you can do is just grow out the seed
you save from them, I'd plant it in a different spot to make sure they are from the saved seed
. I would love to help you grow them out
if you do decide to save seeds
from it. I love the look as well and it's not like I am addicted to them, but I did buy 5 diferrent varieties of them last year planted 2 types fairly close, I'm now hoping maybe I'll get some sort of cross.
