A sadly spindly ‘mystery tree’ grows on a steep slope in our back fern garden. I first noticed it six or seven years ago. Its top was broken off in a winter snowstorm a while ago, and its odd growth pattern, plain looking leaves and immature bark left me clueless about its identify.

For most of human history, families relied on gathering foods growing in their environment for some portion of their diet. And many of these delicious and nutritious foods grow on long-lived trees or shrubs, from persistent perennials, or from plants that readily self-seed. This very sustainable form of agriculture allows for food production with few inputs of water, fertilizer or labor, once the plants establish. Perhaps most importantly, there is minimal disturbance to the soil’s ecosystem.
