Leach Botanical Garden Plants and History – David Porter, Director of the Leach Botanical Garden  www.leachgarden.org


12 Leach garden-Kalmia latifolia 'Elf' Photo - Scott HoelscherA lush oasis just south of Foster on SE 122nd, the historic Manor House and grounds of Leach Botanical Garden lie in a hollow carved out by Johnson Creek. In 1931 John and Lilla Leach purchased five acres along Johnson Creek and named it “Sleepy Hollow”. Here they built their home and devoted themselves to their love for plants. The original Leach collection, which includes Kalmiopsis leachiana – one of five plant species discovered by botanist Lilla Leach, forms the core of the now 16+ acre botanic garden. Leach Botanical Garden, a model of sustainable and natural landscaping, is dedicated to the conservation of and education about northwest native plants. David Porter will talk about the lives of John and Lilla Leach and the importance of this beautiful garden to gardeners everywhere.

David Porter has a wealth of experience in non-profit management, having served as the Executive Director of organizations as diverse as Pioneer Courthouse Square and the End of the Oregon Trail Interpretive Center. David has a special appreciation for the importance of irreplaceable collections and the opportunities they create: “The stories, whether of John and Lilla Leach or of the plants in the collection, make it possible to spark the imagination and create insights and dialogues on a wide array of topics, connecting our past and our future with the natural world around us.”
