Central Park Gardens feature a broad variety of regionally-appropriate plants: wildlife-attracting, native, and drought-tolerant plants. 
The long, narrow site is well-suited for separation into several distinctly themed "garden rooms" that visitors can stroll between.
The UCCE Master Gardeners of Yolo County volunteer here and are involved with design, plant selection and public education at the gardens.
Come visit us in Davis Central Park, on B Street between Third and Fourth Streets in Downtown Davis.
