An Herb Spiral is a spiral of rocks enclosed in a pile of soil in which many species of herbs are planted. The rock warms and dehumidifies the soil. The greater surface area, provided by the mound of soil and rock, wrapped in on itself, provides a wide diversity of growing conditions creating high productivity in a small space. The dry-loving herbs are placed near the top of the spiral and the water-loving at the bottom. An herb spiral is easy to water and harvest-- plus, it's fun to build and looks nice!
