NEVER plant this outside of a non-draining container. I made the mistake of planting a few, and had to rip out an entire bed to try to get rid of it. In one year, it had spread at least 5' in every direction.
The roots are tiny, fibrous rhizomes that are impossible to pull out completely, so controlling it is impossible.
It's a pretty plant, and a great looking alternative to grass, but I'm really surprised that it is sold in the trade, because of its invasiveness.
BEWARE.
