In north Phoenix, an area called Sunnyslope, is the oddest, quirky, most unique house landscaping I've seen. The hours owner Grover Cleveland Thompson must have put in during his 22 years in the house is numbing. Grover Cleveland moved to Phoenix in 1952 and continued to build his rock garden with pouring concrete in halloween masks (which is why some of them seem pretty scary to me) and Fiestaware until his passing in 1978. I spoke briefly with the lady there (possibly the owner? ) and she said she doesn't add to it with the exception of adding more necklaces to the busts.
For more information and to read letters written by the Marion, the owner after Grover, click here. There is even a reply from Arizona Highways regarding a letter Marion wrote to the magazine.
The garden is open the first Friday of the month from 2-6pm. Otherwise you can see a small portion from the perimeter fence. The address is 10023 N. 13th Place, Phoenix, AZ. Directions: I-17 exit 207. East on Dunlap Ave. for three miles. Turn north onto Cave Creek Rd for one mile. Turn right onto E. Cheryl Drive (a small street), then an immediate right onto N. 13th Place. The Garden is halfway down the block, on the north side.
