As our approach to food becomes more and more centered on nutrition and sustainability, we are inevitably going to look into new (and old) ways for filling our dinner plates. When we think of greens, most likely, lettuce, cabbage, and kale come to mind. More adventurous diners might have delved into dandelion greens or stuffed grape leaves. However, very few of us have looked to the most abundant source of leaves: trees.To be honest, most trees with edible leaves have dubious reputations. Tree leaves, like most wild sources of food, tend to be much more robust in flavor and often tougher in texture. On the positive side, those with leaves that aren’t particular brutal on the taste buds will provide a lot more food per square foot than will Swiss chard or mustard greens (not to say we shouldn’t be growing these, too).In permaculture, and more so nature, trees are integral to healthy eco-systems. They are perennial plants that provide habitats for animals, supply mulch material for soil (and soil life), prevent erosion, help with moderating temperatures, increase moisture in the atmosphere, and clean the air. In other words, they have a lot of uses, with edible leaves being yet one more viable way to justify planting that forest garden in the backyard.
