San Francisco benefits from California’s Mediterranean climate, characterized by mild wet winters and warm dry summers. While our summers are not always warm, they are dry. We suggest using the drought-tolerant and low-maintenance plants in this list to add color to your garden while still helping to conserve water.
This list was provided by the Department of Public Works' Bureau of Urban Forestry. For more information about landscaping with drought-tolerant plants contact the Garden for the Environment.
