During nearly a quarter-century of work, Gayle Engels has gotten her hands dirty in many herb gardens. The director of development of gardens at the American Botanical Council has worked on children’s herb gardens, gardens for herbs that benefit body systems, healing herb gardens and raisedbed herb gardens accessible to people in wheelchairs, among others. Engels’ current focus is an herb spiral in a 15-by-15-foot space in a Beaverton, Oregon, community garden.
