With its mossy tree stumps and fern-covered logs, this Vashon Island, Washington, garden looks like it was lifted intact from a Northwest rain forest. But it’s a stumpery—similar to a rock garden, but built with tree parts. Owners Pat and Walt Riehl brought in madrone and Douglas fir stumps from construction sites on the island, which fern expert Martin Rickard placed among existing trees. Then they added tree ferns (Dicksonia antarctica), spotted may apple (Podophyllum ‘Spotty Dotty’), and Tolmiea menziesii. Call it recycling, nature-style.
