Since it is too hard to move a rock..then why not decorate it.  That is what I did with mulch, flowers and different types of grasses.  We have several large rocks I have had to deal with.

I love purple, so these purple flowers are some of my favorite.  They are soon to be moved into my butterfly garden.  Due to the number of flowers in my yard, I have a great supply of "Humming Birds" and Butterflies.  We feed birds year round and have many different types of colorful ones that hang around the yard too!
