University of California, Irvine Arboretum

The University of California, Irvine Arboretum is a botanical garden spanning about 5 acres that displays plant species from California and South Africa. The collection represents different plant communities and is maintained by the university for teaching and research purposes.

The arboretum was founded in the 1960s and has focused on preserving plant species native to California, including varieties from the Channel Islands and Baja California. This focus reflects the university's commitment to documenting and understanding the region's plant life.

The arboretum serves as a teaching space where university students and faculty conduct research on plant biology and regional ecosystems. Visitors can observe how the grounds are used daily for scientific observation and hands-on learning.

Entry to the arboretum is limited to university employees, staff, and students, though the public can visit during quarterly open house events. Plan your visit ahead to make sure you catch one of these special opening dates.

The grounds feature an extensive collection of aloe plants that often goes unnoticed by visitors, despite showing numerous varieties. This collection offers rare chances to see and compare different aloe species outside their natural habitats.
