Potomac Landscape Designers, Bethesda Landscape Architects

Who We Are


We're a Potomac, Maryland based landscape design and architecture company founded by Susan Pumphrey, a graduate of the University of Maryland's Landscape Architecture program. From our early roots as a small boutique design firm, we have evolved into a full service design, construction and maintenance company specializing in landscaping projects in Potomac, Bethesda, Rockville, Kensington, Silver Spring, and Washington DC. We also service the great Montgomery County, Maryland area.

Susan and the entire Kalyx Green team have a passion for design and find joy in seeing it come to life for our clients. Our goal is to give back by bringing ideas and dreams to life while enhancing the environment.

We area a full service general contractor. In addition to landscape and hardscape design, we specialize in interior remodeling and home additions.

Why 'Kalyx Green'?

calyx is the first part of a flower to form. The calyx protects the developing bud as it grows and forms the structure that supports the petals. Though it is often green, a calyx may be any color depending on the plant.

Think of Kalyx Green as a nurturing calyx for your landscape, hardscape or home renovation project. Our team will work with you from start to finish, helping you realize your vision for your property.
