I've grown this plant for years and it's a great one. It seems to me to be fairly widely available. Ambergate (Victoria), Highland (St Paul), Kelley and Kelley (Long Lake) and Funkie Gardens (Prescott, WI) seem like like sources. They're all worth a visit anyway.

Good luck, and if you find it buy several - they are long lived and don't need regular division.

Thanks Ted...

I will look up those nurseries and bookmark them...
