It was a cool, wet morning so I was not surprised to find bees sleeping on the liatris. Actually, I was happy to find them sleeping because when they are awake they fly around too much for me to get a good photograph of them.
Five years ago, we planted a small native wildflower garden in our back yard. Every year we add more native wild flowers. One of the first plants we planted was Purple Coneflower (Echinacea angustifolia). They have established themselves and are slowly spreading.
A frequent visitor to the coneflowers are Monarch butterflies (Danaus plexippus).
