At this 135-acre outdoor, living museum, you can also explore the Hummingbird Trail to seek out the rare, elusive white hummingbird, and sniff pleasing scents of lavender, jasmine, and oregano in the fun Aroma Garden.
The UC Santa Cruz Arboretum & Botanic Garden’s rich and diverse collection contains representatives of more than 300 plant families of Mediterranean climates. The garden maintains collections of rare and threatened plants of unusual scientific interest. Particular specialties are world conifers, primitive angiosperms, and bulb-forming plant families. Large assemblages of plants from Australia, New Zealand, South Africa, and California natives are displayed on the grounds. Many of the species in these collections are not otherwise available for study in American botanical gardens and arboreta.
