I think about it every winter when I start worrying about protecting it from the cold, but it hasn't been bothered yet. My problem is anywhere I'd plant it, it would be amongst the goldurned oak tree roots, and there would probably be no rescuing it if I decided it was a bad idea. So . . we carry on in the same pot just refreshing the soil every second year (well, this year is the first time I did it) and moving any babies that appear.
I have two little ones like what I sent you, but Swayback seems to have gone astray and I was saving them for him. Anybody heard from him? I wrote him a Tree Mail a few days ago.
