It is easy to see why. From a wide terrace spanning multiple rooms in their red brick ranch home in Des Peres, two staircases descend to a jewel-like swimming pool that glitters sapphire blue. Although the space is small, it is picture-perfect. Stands of columnar DeGroot’s Spire and Emerald Green arborvitae, interspersed with burning bush for fall color, provide a buffer from neighboring property. Graceful, billowing Karl Foerster Feather Reed Grass and pyramid-like Golden Threadleaf false cypress soften a wooden privacy fence.
