I'm in the middle of relandscaping two yards - quite the endeavor. I was looking for more specialized plants (for example, drought tolerant) that you often can't find at your Walmarts or Home Depots.
Sun River had a wide selection to choose from. I saw a lot of plants that I had not been seeing at the other garden centers. The plants were large and healthy.
It is a bit more expensive than some other places like Home Depot, but it is worth it to shop here for the selection and quality.
