Benny,
I got a basjoo from a friend in Oregon.
She used a long, thick, 5 inch diameter cardboard tube - kind of like what architects use.
I can stand on it and it won't collapse.
Don't know where to get them, sorry, I know that doesn't help you.
She lined the leaves with newspaper & had crushed paper to support the stem & the root was moist newspaper & plastic wrapped.
They showed up with all their leaves & unscathed!
Hope this gave you some ideas!
