Katrina, to clarify, UCBG and Tilden are in Berkeley and Merritt College is in Oakland.
Agree with Blake — the Merritt program is great. I also volunteered at Tilden’s native nursery on Thursday mornings — propagating, etc. It was a great way to learn about natives. U.C. Botanical Garden and the Tilden Park (native) Botanical Garden are both stunning places to check out CA natives in a park setting.
