Established in the late 1970s by the Point Loma Garden Club and the California Native Plant Society in partnership with the City of San Diego, the Point Loma Native Plant Garden spans 2.5 acres of labeled native habitat at 2275 Mendocino Boulevard. The garden occupies the western section of Collier Park, managed by the San Diego River Park Foundation and maintained entirely by volunteers through a twice-monthly Garden Club workday program. Its collection features rare and endangered species native to the San Diego River watershed, including several plant varieties found nowhere else in the world outside this coastal region. Walking trails thread through labeled stands of coastal sage scrub, manzanita, toyon, wild lilac, and Torrey pine specimens, with an observation platform built by local Boy Scout troops. An on-site nursery propagates cuttings and seedlings harvested from the garden itself, giving visitors a living reference for drought-tolerant California-native landscaping just uphill from the coastal bluffs preserved at Sunset Cliffs Natural Park. Guided restoration events tackle habitat projects like erosion control, invasive-species removal, and riparian buffer planting along the nearby San Diego River estuary.
