Caroline Cobb Ervin, a landscape and garden designer in the metropolitan Washington, DC area, studied landscape design at George Washington University. Since 2007, she has worked closely with her clients to design, install and maintain both large and small residential gardens throughout the metropolitan area. Travels to gardens throughout the United States and Europe have added to her design background and understanding of historical gardens. More than 20 years of hands-on gardening experience gives her additional understanding and knowledge of soils, plants and diseases. When not designing, you can find her digging in her garden, dirty fingernails and all.
