Rolling out another older great thread.
I picked up a few last spring and they were slow growers .
I have them in the basement as an understory plant.
They have tolerated 90 days on dim light with a few lost leaves
They also seem to be somewhat prolific filling the containers with offshoots.
I have not inspected the plants yet to see where I might separate them.
They have a nice unique shape too.
