I have a multi plant P. 'Xanadu' growing out in the garden that now takes up 10' x 12' of ground. This plant covers 1' of my back walk space now. I am thinking of removing it but now think maybe I can just cut it to the ground and have it return from old remains. Anyone have experience with cutting one back like this?

I'd, just trim it back from walkway.

Wish I could grow Thaumatophyllum xanadu in the ground; mine has always been in a container due to the fear of a freak freeze.

Philip, It will not be a pretty sight cutting it back from walkway as all you would then see is stems with roots down to the ground.
Lin, My plant has endured many freezes without major damage. I covered it when it was smaller to protect from frost and freezes but haven't in years.

How about just thinning it out, digging out portions of it? And passing it along, of course. Mine is in a pot for the same reason @plantladylin

Parting the foliage this mess lays beneath.

That mess is what made me remove Xanadu from my garden. It was a space hog and there was no way to gracefully trim it. Beautiful plant, though.
