Who We Are
Landscape Design Associates is a small, locally-owned business offering landscape design, planting installation, and container gardening services in the DC metro area. We operate from Treefrog Nursery in Great Falls where many of the plants used in our installations are grown.
Founded in 2004, the nursery grows a wide selection of annuals, perennials, and shrubs, concentrating on native species known for outstanding performance in local residential settings. We use no pesticides, herbicides, or fungicides on our plants, relying instead on diversity of product and natural resources to alleviate any problems which may occur. The nursery also supplies plants to local homeowners. For more information on our environmental policy please click here .
Led by Joanne Shumpert and Katy Lellelid, Landscape Design Associates offers an opportunity for qualified independent landscape designers to work together, sharing knowledge & design ideas, and pooling resources such as plant sourcing and installation services.
Joanne has operated Treefrog Nursery since its inception in 2004 and has completed the graduate program in Landscape Design at George Washington University. Formerly an electronics & software engineer, she started her gardening career in the gentler climate of southern England. She has lived in Virginia about 15 years and is a Virginia Certified Horticulturist.
Katy has a master’s degree in Landscape Design & Sustainability from George Washington University, having completed both the Landscape Design and Sustainable Design certificates. Katy’s first career was as an economist, but she is now committed to excellence in landscape design, specializing in native plants and sustainability.
Edye has been an avid gardener and landscape planner for over 35 years. Moving to Virginia 11 years ago after having lived in Arizona and the mountains of New Mexico most of her life, there was a whole new world of herbaceous plants and trees to learn! She completed the graduate program in Landscape Design at George Washington University and has been an active Loudoun County Master Gardener/Tree Steward volunteer since 2008. Her special interests include incorporating more native plants and water-wise gardening.
