The Secret Marvels of Spring

As we move into spring, color is beginning to permeate the landscape once again. New blades of grass are pushing through the brown thatch, in shades of green so bright they are almost hard to look at. A smattering of oranges, yellows, and purples freckle the hills: flowers announcing their presence to insects looking for their next meal. Like the insects, people flock to see the flowers, as well. Admiring their beauty, we are reminded of spring’s ability to make us feel renewed.

In Contra Costa County, the wildflowers we find are often hidden—tucked away in small pockets, inviting us to search intently for them. Invasive annual grasses are forcing wildflowers into smaller and smaller patches each year. Spring wildflowers play a vital role providing nectar and pollen for pollinators and birds during a time when they need a lot of energy to reproduce. Because of invasive grass dominance, pollinators must compete over isolated wildflower patches, resulting in population decline of both wildflowers and pollinators.

Despite this decline, it is still very possible to see native wildflowers and their pollinators this spring, and perhaps their rarity makes finding them even more rewarding. Below are some wildflowers you can find in Contra Costa County, some of which you may have never noticed before!


Californiagoldfields (Lasthenia californica)

California goldfields are often one of the first wildflowers to bloom in early March. In large numbers, they form bright carpets that are impossible to ignore! These large patches are a clue that the soil below is low in the nutrients that invasive grasses need to survive. Goldfield seeds are harvested by Indigenous people to make pinole (seed paste).

Where to spot them: Black Diamond Mines Regional Preserve, Morgan Territory Regional Preserve, Briones Regional Park


Magentared-maids (Calandriniamenziesii)

Magenta red-maids are another early bloomer. Their delicate purple flowers are a delight! As a fire-following species, Indigenous people used to set fires to promote their germination so that they could later harvest their seeds.

Where to spot them: Fernandez Ranch in Martinez, Briones Regional Park, Diablo Foothills Regional Park, Morgan Territory Regional Preserve, Carquinez Strait Regional Shoreline


Elegantclarkia (Clarkiaunguiculata)

Clarkias bloom in late spring to early summer, providing pollen and nectar to insects later in the season, when most flowers have gone to seed. They serve as the host plant for the Clark’s day sphinx moth. Look for this charming flower in the shade of an oak tree.
