Leach Botanical Garden

Portland, Oregon, United States

---

Leach Botanical Garden is a 16‑acre public garden in outer southeast Portland, Oregon, located along Johnson Creek on 122nd Avenue near Foster Road.

It began in the 1930s as the “Sleepy Hollow” home and private garden of botanist Lilla Leach and pharmacist John Leach, who built an extensive collection of native and exotic plants on the property before donating it to the city in 1980.

The garden opened to the public in 1983 and now features winding paths through creekside woodlands, meadows, and steep slopes, with more than 2,000 plant types including ferns, camellias, alpines, medicinal herbs, and many native Pacific Northwest species.

A highlight today is the elevated Aerial Tree Walk, which lets visitors stroll through the forest canopy, alongside newer features such as a four‑season pollinator garden and art‑infused spaces that blend horticulture, habitat restoration, and community programming.
