Yarrow is a very special flower used for drying.  I use it in my arrangements.  Love growing it because it just takes care of itself without much care at all.  It dries to a beautiful bright yellow and holds its color when picked at the right time.  It took me a couple of years to learn that, but once you see it with that look then you got it.
  It can be used with any color scheme.  It simply makes a room pop.
