In 1964, Stewart and Audrey Barber began what was to become Sonoma Horticultural Nursery with an emphasis on growing and hybridizing Exbury Azaleas. When Polo de Lorenzo and Warren Smith purchased the nursery in 1976, it consisted of the gardens by the house and the growing grounds which is now the parking lot and lath houses. At the time, the rest of the property was overgrown with nettles and blackberry vines. Over the years, Polo and Warren have stabilized the banks of the spring-fed pond and Blutcher creek and cleared away the weeds in order to create the gardens that exist today. There are now seven and a half acres of gardens and nursery with over one and a half miles of pathways for you to explore & enjoy.
