"Lilla Irvin Leach was born March 13, 1896 on a farm in Barlow, Oregon. Lilla was educated in public schools in Barlow and Aurora, at the Tualatin Academy, and at the University of Oregon in Eugene, where she studied under Albert R. Sweetser. In 1913, Lilla married John R. Leach, a Portland pharmacist. Together the two roamed the interesting botanical areas of the West, concentrating on the back country of the Siskiyou Mountains. Aiding them in their travels and collecting were the two famous burros, Pansy and Violet. Lilla is credited with discovering 15 new species and two new genera. Her most famous find was Kalmiopsis leachiana, which she discovered in 1930. The Leach Garden in Portland is the former home andgarden of John and Lilla Leach, a place they called Sleepy Hollow. The private life of Lilla Leach remains something of a mystery. Lilla and John were childless, but it is known that her sister, Clara, had children; however, attempts to locate them or their descendants have not been successful."
