Peeking into Permaculture:Multi-tiered landscapes of native food-producing plants an emerging trend

摘要

North American's desire for more attractive properties, fueled by more disposable income and increased leisure, has driven our industry's growth post WWII. The industry responded and became expert in beautifying and, in many cases, designing and installing more recreationally functional outdoor environments in residential, commercial, governmental and industrial settings.But the public, composed of consumers with widely diverse desires, keeps raising its expectations and demanding an ever-wider range of outdoor property services. Increasingly these demands are allied to ecological and environmental concerns. Consequently, landscape contractors are being tasked to meet these. This is especially true in terms of landscape design and plant selection. This challenge may even include the incorporation of native and edible plants into clients' landscapes.
