We have an area about 28' in diameter around an oak tree under which we plan a flower bed. This area is surrounded by a circular driveway. It is elevated an average of 12-16 inches. We are not interested in RR ties or landscape timbers. We would like to make this real attractive since it is in the driveway and very visible. Looked at the local Lowes and found that the "stones" they offered were going to run into quite a lot of money for all the material we need.
Just wondering if anyone has any good ideas on what to use as a border.
Thanks
