Support Us

As a fully “member and volunteer powered” organization, we invite you to participate in our ongoing efforts.​ Donations are tax exempt under IRC section 501(c)(3), federal tax ID #51-0178003.
SMAS accepts plants and pots/containers. However, SMAS no longer accepts chemicals such as synthetic fertilizers or pest insecticides. SMAS has been using organic materials for a few years. You can take to these items to the San Mateo County Toxic Waste Drop Off, 32 Tower Road. You must have an appointment. They are open Thursday, Friday, Saturday only.
​Our mission is horticultural education and our passion is connecting people  
and plants to enhance the community.

  • Become a Volunteer
    Volunteers provide the work for all our activities and functions. Expert skill level is not required – simply a desire to contribute to the Arboretum Society’s mission. 

  • Order Tribute Bricks
    Purchase engraved, personalized bricks for permanent placement along the pathway in the Butterfly-Hummingbird Garden has now been expanded to the Rose Garden. The revenue from this campaign supports our mission to educate the community and maintain and enhance several Central Park gardens.     We make every effort to install tribute bricks quickly. But, the typical time to install a tribute brick is 2-3 months as we depend on an outside vendor to create them.
