A tree-focused educational garden sits along Balboa Drive at the western edge of Balboa Park, where Trees for Health Garden curates labeled specimens of medicinal, fruiting, and culturally significant tree species drawn from California native and international stock. The collection sits a short walk from the brewery taproom at Pure Project Balboa Park, anchoring a Balboa-edge loop that mixes botanical study with park-side dining. Interpretive signage at each specimen covers the tree's common and Latin names, native range, traditional medicinal uses, and notes on cultivation in coastal Southern California's climate zone. Self-guided visits work for casual walkers, while school groups and herbalism students use the garden as a field-study site for tree identification and ethnobotany coursework. The Balboa Drive location places the garden directly along one of the park’s primary walking corridors, a position that makes it a frequent stop for guests staying at heritage Sixth Avenue hotels like Inn at the Park during multi-day Balboa Park visits. Volunteer-led restoration days are the garden's most involved project — full-crew sessions handling pruning, mulching, irrigation repair, and replanting on the multi-acre slope to keep the labeled collection viable through dry seasons.
