Gardening has always been Terry Metzler's favorite hobby, while her husband, Steve, enjoys keeping fish. So they decided to create a pond in their St. Louis backyard that would cater to each of their interests and provide an ideal backdrop for entertaining family and friends. It wasn't easy. Digging the hole was the hardest part; they had to use a jackhammer and pick ax to chip into the bedrock. The whole project took two years. Now their pond is stocked with koi, water lilies, and lotus, and surrounded by 300 varieties of hosta, more than 100 kinds of daylilies, and hydrangeas, azaleas, and rhododendrons.
