MBBG is a 501c3 non-profit organization. Our mission is to promote a revolution of Earth-friendly gardens in the South Bay and your support helps make that happen!

MBBG's demonstration garden is located in Polliwog Park. It showcases California native plants and is a tool used when working with volunteers including students, seniors, disabled adults, parents, scouts, and work-place groups. The garden is also a great place to visit and picnic. MBBG maintains an educational website, offers free gardening classes in spring and fall, and participates in local events. The all-volunteer run organization thanks you for your generosity!

By providing your address we can mail you a membership card which can be used to receive discounts at local nurseries. 

We are a small non-profit organization run by volunteers. We do not share contact information with any person, organization, or entity, without expressed consent.


Support your local garden. Membership donations go towards tools, seeds, new plants, and educational materials.
