The SHRF was instrumental in developing the ornamental landscaping familiar to Californians today

The Foundation conducted research into plant quality and propagation methods, evaluated trees and woody plants for street and shade planting, established test sites for investigations into climate and cultural techniques, and ultimately patented varieties of magnolia, Chinese pistache, and olive trees. The Foundation also investigated plants from Australia, New Zealand, and Chile as potential low-water-use and fire-retardant introductions to California gardens.
