Sasa veitchii is a miniature bamboo that makes a perfect groundcover while providing ornamental shape at the same time.
it other key feature is the 25cm long leaves that are mid green with a contrasting cream edge - the end result is very attractive when planted en-masse. Though it should be pointed out that this is a rhizomatous 'running' bamboo and will therefore take over any available space in time so efforts need to made to contain it.
