The Leaches traveled across the Northwest in search of finding new plant species and better understanding the climates that they live in. In a book written by John, Oxbows and Bare Feet, he discussed that he and his wife found 15 new plants and 2 new genera in the Oregon area. The most famous discovery was the Kalmiopsis leachiana. This plant was discovered in the area now named for the plant, Kalmiopsis Wilderness, and is named after Lilla.
Both Leaches were awarded for their efforts in the community and botany world. Lilla won an American Botany Award among other awards for her efforts. John helped his community very much and was a major contributor to getting civil work done in the surrounding area. He also has a YMCA named after him for his support of the program.
Today, you can adventure and walk trails through the property. You can also go inside the buildings that John and Lilla once called home. There are many events now held at the botanical garden as well as guided tours.
