History of Leach Botanical Garden

The property was originally part of a 320-acre donation land claim belonging to Jacob Johnson, one of the sawmill operators who was furnishing lumber for the very early homes in Portland. Johnson's land extended from Mt. Scott down across the creek that was later named for him. In 1931, John and Lilla Leach purchased part of what had been Johnson's property and named it Sleepy Hollow. John, a pharmacist, and Lilla, an accomplished botanist, devoted their land to their fascination with plants.

Discovery of Kalmiopsis leachiana

Lilla discovered five plant species new to science. One of these species dates back 10 million years ago; it was given the Latinized form of its discoverer's name, Kalmiopsis leachiana. John Leach was also a talented craftsman and very proficient at metalwork (some of his work is on display at the Garden). He was active in the Oregon Arts & Crafts Society and served as president.
