Founded in 2009 by certified landscape architect Sarah Mitchell, our company specializes in creating sustainable, low-maintenance gardens that reflect each client's unique vision while working harmoniously with local ecosystems.

Our comprehensive approach combines scientific plant knowledge with artistic design principles to create gardens that are not only beautiful but also environmentally responsible. We believe that every garden should tell a story, provide habitat for local wildlife, and bring joy to those who experience it.

From initial consultation to final installation and ongoing maintenance, we guide you through every step of your garden transformation journey. Our team holds certifications from the American Society of Landscape Architects and specializes in native plant gardening, permaculture design, and sustainable water management systems.
