Thanks Tee. Silver Carpet has a much nicer habit my Stachys. I particularly like the larger, more upright leaf. Blue Dune is such an intense blue. I don't recall seeing anything like it before. I have blue fescue and Schizachrium scoparium ‘The Blues’. Both are a duller blue. I like the stiffness of the blades in your photo too.
Tamara, how do you maintain your phlox to get such an amazing flower display?
