A journalism major from Stanford University, Della Taylor Hoss always considered art to be her avocation. She was a perpetual student. She first learned etching and woodblock printing in a commercial art studio in San Francisco, then enrolled in classes to hone her skills. Later, she studied in Seattle with Mark Tobey, who taught her "rubbed graphic drawing," a process she would use throughout her artistic life. Between 1928 and 1942, Della lived in Yosemite Valley while her husband, Herman Hoss, was the federal magistrate and treasurer of Yosemite Park and Curry Company. She studied with Chiura Obata, University of California emeritus artist, who taught Japanese Sumi painting in Yosemite Valley. She also collaborated with her botanical mentor, Mary Curry Tresidder to write Trees of Yosemit,e for which she created 34 intricate linoleum block prints of trees and cones.

In her 70's she travelled to the White Mountains to see the Bristlecone Pines with a friend. Della was awestruck by the beauty of these 4,500 year old trees. The experience was the climax of her lifelong love affair with the trees. She created a series of 15 stunning colored pencil charcoal drawings capturing the life and death struggle of these amazing trees.

Della continued to enjoy her family, friends, trees and to work in her Palo Alto studio dubbed "My Creative Oasis" creating etchings, linocuts, woodcuts, drawings, limericks, calligraphy, and clay sculptures until her death in 1997.
