Lamb's Ear, or stachys byzanina, are mostly grown for their gray/silver green leaves with fuzzy texture.  Great for children, they are really marvelous and fun to touch.  They are "deer resistant," but I use that term loosely!  According to the Better Homes and Gardens site: "Lamb's ears is a top pick for a groundcover in a hot, baked spot. Its silver felted foliage quickly forms a dense, delightful mat. It also contrasts nicely with other foliage and most flowers, enhances almost everything." 

Rose Campion

Rose Campion, or Lychnis coronaria (or "catchfly"), is often mistaken for Lamb's Ear because of its color and texture but the leaves are narrow and it has long, hot pink 1" bloom in late Spring (on stems that can grow as tall as 3') with a long blooming season.
