Emory Knoll Farms, dba Green Roof Plants, is a long-standing leader in the green roof industry (since 1998), providing the highest quality in plants, knowledge, and service for green roof projects across the U.S. and around the world.


Our nursery is located on 150 acres of conservation farmland in Maryland, on the East Coast of the U.S. Our nursery operations and business practices are founded on the core ideas of long term economic, social, and ecological sustainability.

Emory Knoll Farms has provided plants for over 1,000 green roof projects, totaling hundreds of acres of planted roofs. As green roof specialists, we are active in green roof plant research and maintain several test roofs at our nursery. We are constantly acquiring and studying new varieties of plants, and collaborate on green roof research projects at educational institutions and nurseries in North and South America, Europe, Asia, and Australia.


We keep over 100 different green roof species and cultivars in our regular inventory, including succulents, groundcovers, perennials, and North American natives. We regularly inventory over 2 million plants, ready for shipping each season. We are the innovators of the most frequently specified Green Roof Mixed Flats, and we carry a variety of mixed flat blends for different geographic regions and design applications.
