Join founder Jeff Lorenz and Sarah Leaskey (RLA) to learn more about their design-build-stewardship approach to high impact, low input ecological landscapes. Passionate about planting a new paradigm in the minds of home gardeners and industry peers, join them to hear how an awareness of sound, movement, responsibly sourced materials and the built environment, alongside functional planting design, can create immersive, expansive outdoor spaces to explore, observe and unwind.
