Il faut cultiver notre jardin Silvora Landscapes was founded in 2020 by Thornton Matheson, who holds a Master of Arts in Sustainable Landscape Design from George Washington University. Silvora designs draw inspiration from the natural environment. The designer works exclusively with local native plants to support biodiversity, minimize maintenance, and celebrate the beauty and richness of native plant communities. Left: T.
