I really like bonsai trees, I have a small garden of them, and try to learn about them as much as possible. Lake Merritt has a really great collection that I have been enjoying and sketching. This drawing is inspired by a sketch I did there of a California Juniper. 

This drawing is also my next submission for Art in a Box, an art subscription service through The Compound Gallery in Oakland. Limited edition giclee prints of this piece are also available, which you can find here
