I've dug every one of the rocks in the pictures out of my flower beds. There are more piles of rocks, including a now overgrown rock garden, in various places around the house. I expect when I dig the holes for the fruit bushes and tree I'd like to order, I'll find more rocks. The whole neighborhood is built on glacial till!
I love how the yellow flower clashes almost entirely with the purple fuzzy foliage :)
