Pink sedum, echinacea, Russian sage, and spiky bright purple liatris in mid-late Summer. The tallest shrub, Eupatorium maculatum 'Gateway' Joe-Pye Weed, is a prairie native, and should do well in the Intermountain West.
An absolutely classic flower for a winter wedding and very seasonal in January. Colours range from burgundy to white and lots of the varieties have a beautiful speckled pattern. Whether you are going for muted or vibrant colours try to include hellebores in your seasonal wedding flowers!
