It gets around, but it's easy (here) to keep under control. Others may have a harder time with it.

Short/Med - Plant 12" apart. Zone 5-8. Great foliage plant. Deep chocolate purple leaves stay close to the ground. Blue purple flowers ring their stiff stems and dry in place to a silver white. Pleasing effect for the foreground.
