It features: California native plants adapted to our local conditions, as well as selections from UC Davis “Arboretum All-Stars” and “Future Favorites” (plants tested for performance in a changing climate). These plants are chosen for their ability to thrive with minimal water, support local ecosystems, and remain reliable under future climate conditions.

Three Sisters & Sunflowers

A vibrant garden featuring tall corn plants, red amaranth, and sunflowers, with distant mountains under a clear blue sky.

Corn, beans, and squash are the “three sisters” planted in this plot, an example of companion planting. Corn provides tall stalks for the beans to climb. Beans fix nitrogen from the air to enrich the soil. Large squash leaves help shade out weeds and retain moisture. Cheerful sunflowers, sometimes considered the "fourth sister," are planted to attract pollinators. In winter, cover crops are planted to improve the soil.

Tomatoes

An assortment of tomatoes in various sizes and colors on a wooden surface, alongside a halved melon and a knife.

In the summer, over 50 varieties of tomatoes are grown on the southern reach of the east fence. Varieties are evaluated by flavor, production, health, and vigor to select tomatoes that do well locally. The tomato beds are either left fallow or planted with cover crops during the cooler season. At our annual Spring Garden Fair, we offer over 60 varieties of tomato seedlings for home gardeners to buy.
