              effort, the Society maintains the Kohl Pump House, greenhouses, 
              garden shop, and rose garden at San Mateo's Central Park, and 
              sponsors educational programs and workshops on gardening, 
              landscaping, and floral arrangements as well as special events 
              such as the annual garden tour.
