The only croquet I was familiar with was the backyard variety where opponents can be knocked one anthers ball into the tall grass when we were asked to landscape the croquet courts at The Chattooga Club http://www.chattoogaclub.com.
The 2 bent grass croquet courts are located on an beautiful setting with a backdrop to mountains, Rock Mountain and Chimney Top.
The landscape around the court consist of an arbor at each end, a hedge runs the length of the two courts and separates the lawns from the view, a 22" tall wall run the length of the opposite side. We used large boxwoods to frame the arbors and steps. and collected old apple trees from the property into an orchard located at one end of thee courts. This scene can be overlooked from an open air pavilion can seat 75. The two are connected by a 30' wide staircase with 11x5" steps.
The only flowers are done in large containers. It is a very simple landscape but has good scale.
