Visit Sonoma Botanical Garden

Located near Glen Ellen, at the heart of the Sonoma Valley, Sonoma Botanical Garden boasts one of North America’s largest and most important collections of temperate-climate Asian plants as well as California native plants. 

Along with waterfalls, ponds, and photo-worthy views of Sonoma Valley, the Garden’s 25 acres house mature flowering Asian trees and shrubs, many of which are rare and endangered varieties, and  a 22-acre parcel of oak savannah and chaparral.

More than 90 percent of the Asian collection was grown from seeds collected during yearly expeditions into the wild regions of the world (mainly China, Japan, Tibet, Yunnan, India, and Nepal). Other trips have collected from parts of North America. 

Sonoma Botanical Garden dates to 1968, when Jane Davenport Jansen purchased 61 acres of land, all sitting on Coastal Miwok land, in Glen Ellen for vineyards. The property was pocked with old rock quarries, which filled with water during heavy winter rains, creating a stream with ponds and waterfalls. In 1987, Jansen started a garden on 20 hillside acres, and originally named it Quarryhill. That same year representatives made their first seed collecting expedition to Asia. In 1988 a nursery was established, and planting began in 1990. 

Added in 1998, the 22-acre Three Springs Ranch property celebrates California native plants. The “living museum” expands the Garden’s environmental educational around the conservation efforts of endangered Asian plants and California native plants.

Some of the varieties preserved at the Garden are threatened with extinction in the wild due to habitat loss, which usually comes about through human actions like deforestation, agricultural expansion, and/or resource consumption. The fact that these plants grow at the Garden, and that their seeds are being saved, increases the chances that they will not become extinct. 

Together, we can protect and preserve the beauty and natural resources of Sonoma County for generations to come. Check out our page on Sustainable Travel, and look over the Leave No Trace Seven Principles.

One example is a maple tree, Acer pentaphyllum, and we have about 50 individuals on grounds. Botanists believe that this plant will be extinct in China within a decade. The Garden grew several hundred from seeds in pots and then replanted them on the grounds. The ultimate goal is to produce seed from the new trees, sending them to China for reforestation. 

Another example is a rose that’s endangered in the wilds of China, Rosa rugosa. It is now widely planted at the Garden. The Garden is also home to many species of Rhododendrons, which are native to both Asia and California.

In addition to rare and endangered plants, the Garden also includes comprehensive collections of wild Asian roses, oaks, maples, magnolias, lilies, and dogwoods.
