Explore Ecology, an environmental education and arts nonprofit in Santa Barbara, has a lot of beautiful trees that would love to come home with you. The trees include: Valley Oak, California Bay, Giant Sequoia, Oregon Ash, Black Walnut, and Button Willow.
The trees are available for a donation to support Explore Ecology's School Garden Program. 

Take one, take them all. They are lovely and really need a home.
