Botanic gardens that center their collections on Mediterranean-climate, drought tolerant plants occupy a special niche in the world of horticulture. Our collections — shaped by these climates from California and the Southern Hemisphere — aren’t just beautiful; they demonstrate extraordinary biodiversity and strategies for surviving dry summers and drought, while providing rich opportunities for research and conservation, and serving an urgent role as public models for water-wise landscapes.
