Bambusa.

Occasionally I sit back and doodle my perfect garden - it's always a place in which the visitor can be peaceful and thoughtful. I've never been one for meditation - though I certainly am one for tea - and I would love to live in a landscape like those of the wuxia films. Some of their most beautiful scenes are in the bamboo forests- to ensure a truly calm environment, I have chosen a non-running species.
