Judith Phillips

Member at Large

Judith Phillips is a founding member of the Xeriscape Council and principal of Design Oasis, a design and consulting service specializing in ecosystem inspired landscapes. Design projects include 1500+ gardens in New Mexico, Colorado and Arizona. Her experience researching and propagating native and adaptive landscape ornamentals informs her work as a designer and garden writer. Although plants are the heart of her design, she feels that extraordinary gardens are more than collections of plants, that the built landscape and the planting should serve each other: the land contours and hard surfaces collecting rainwater to supplement planting, trees shading walls and paving. She is an advocate of landscaping with native and xeric plants because resilience is our hope for a greener future. She has written five books and numerous articles encouraging people to garden with a passion for the high desert, speaks regionally on water conservation, native and arid-adapted plants and design, habitat gardening and related subjects and teaches a plants class in the Landscape Architecture Program at the University of New Mexico. www.judithphillipsdesignoasis.com
