Join Pacific Horticulture for an autumn weekend in the bucolic Russian River Valley as we explore the power of gardens in the context of their natural surroundings. This important summit features nationally renowned speakers from across the horticultural horizon and offers visits to superb gardens that respect the region’s watershed.

Summit 2016, the latest in our Changing Times, Changing Gardens seminar series, is for anyone eager to support the environment within the context of engaging, lively and resilient landscapes.
