Uncommon and Special Trees to Promote Diversity in Yards, Parks, and Open Spaces 2016 List

Uncommon and Special Trees to Promote Diversity in Yards, Parks, and Open Spaces. San Francisco has a unique climate with multiple microclimates, where our open spaces (including parks, private yards, and open spaces under federal jurisdiction, such as the Presidio) present an opportunity to plant a wide variety of trees that are not yet common here. Many of these trees are not well suited as street trees, because they cannot tolerate compacted soils or their canopies or root systems cannot easily adapt to fit within street-side infrastructure. The following list of trees are considered well-adapted to San Francisco’s climate and conditions, but are under-represented in our open spaces. They present an opportunity for experimentation and improving San Francisco’s urban forestry diversity. Though some of these species may be difficult to find, the Urban Forestry Council recommends considering these species to add diversity to the urban forest. To view many of these trees in person, visit the plant collections at the Botanical Gardens at Strybing Arboretum. Updated August 2016
