I just purchased this small catmint at the Arboretum sale in the spring and planted it early May 2013. At 12-18" with a mounding habit, it seemed a good fit for my small butterfly garden next to the patio.
Of course it was a tiny sprite when I planted it. Not anymore.
Compact perennials was what I was looking for and I'm pleased with this perennial so far. It has a pretty shape and the short strands of delicate light pink flowers edge the patio nicely. I'm eager to see how this plant grows and fills in.
