Mixed fountain grasses plus pee gee hydrangea, white echinacea ("White Swan"), plus possibly some oak leaf or Annabelle, plus possibly low white carpet rose. Maybe add Icicle White Veronica or similar. Do Russian sage and grasses near steps.
Sedum, Great use of plants to break up the edges of this deck. The combination of Sedum spectible and the grasses creates a real softness to the planting scheme. Pinned to Garden Design by Darin Bradbury.
