Bay Area’s wildflower season could be the best in years

Love wildflowers? This year could be one of the best yet.

“I think this is going to be the best spring in terms of diversity and flowers in Northern California – and probably the entire state – in 20 years,” said Seth Adams, land conservation director for the nonprofit Save Mount Diablo.

This spring’s eclectic weather, featuring rain, snow, flooding and hail, actually benefits wildflowers, which thrive on the ecological adversity California has recently encountered.

“Three years ago, we had giant fires on four sides of the Bay Area and almost no rain. The next year, we had really heavy, early rains that then stopped, and now we have so much rain it’s record-breaking and flooding,” Adams said.

“Now, a lot of the areas that have the best wildflower blooms are places that’ve burned or have disturbed ground from erosion. So the state’s taken a big drink of water, and we’re going to see regeneration in all kinds of places.”

Tsunamis of brilliant-orange poppies, shimmering hills of yellow mustard, vast oases of color in sparse desert regions – despite cold weather pushing it off, California’s wildflowers are coming soon — and many are already here.

“Since California was fortunate to receive more rain last fall and this winter, public land managers are expecting ‘good’ to ‘better-than-average’ wildflower blooms in spring, depending on the continued weather conditions,” the California Department of Parks and Recreation recently announced. “Depending on the park, visitors may see colorful California poppies, sand verbena, desert sunflowers, evening primrose, popcorn flowers or desert lilies.”

In Marin, Carolyn Longstreth, a board member and field trip leader for the Marin chapter of the California Native Plant Society, said visitors should temper their expectations for this year’s blooming season. She said the cold weather has appeared to delay some of the typical March blooms, but conditions could change.

“I know there is a lot of talk about a ‘superbloom’ on the internet but I think that is probably not the term for this year,” she said. “It’s going to be a good year but it’s probably not going to be amazing.”

Kristin Jakob, another member of the native plant society, said she expects the blooms to last longer — possibly into mid-June.

“There is so much soil moisture that I think it will prolong the blooms,” Jakob said. “The few places I’ve gotten to, I’ve seen greater abundance, especially species like buttercups, and greater masses.

The wooded peak of Mount Tamalpais State Park experiences all kinds of blossoming in April and May.

Expect to see California poppies, purple lupine, narrow-leaf mule’s ear, violet Ithuriel’s spear and blue dicks.

“Mount Tam is always great,” said Alexis Jones, supervising ranger at Trione-Annadel State Park in Sonoma. “Easy Grade Trail is an excellent option for wildflowers, and the Coast View Trail has great options.”

For Mt. Tam, Longstreth and Jakob also recommend areas such as Old Stage Road, Rock Spring Trail and Barth’s Retreat picnic area. Other areas known to have blooms include the Julian Trail in the Marin Headlands, the Ring Mountain Preserve near Tiburon and Mount Burdell near Novato.

“They’ll probably be better than ever this year and last longer,” Jakob said. “Some things are blooming on schedule.”

Longstreth said the special feature of California’s flora is its annuals, including tidy tips, baby blue eyes, red maids and poppies, among others.

The California Native Plant Society hosts wildflower field trips, with more information at cnpsmarin.org.

Point Reyes National Seashore also has popular wildflower sites, including some already blooming at Chimney Rock. More are expected to bloom at areas including Tomales Point and Kehoe Beach in the coming weeks.

“It is going to be a few weeks but every third to fourth phone call we’re receiving at the park is folks asking about the wildflowers,” said Christine Beekman, the park’s chief of interpretation.

Wildflower sites abound elsewhere in the Bay Area as well. A look at spots beyond the North Bay:

Diablo Range, East and South Bays

“All across Mount Hamilton is one of the best places to see wildflowers in the whole Bay Area,” Adams said. “I would encourage people to check out Mines Road, Mount Hamilton Road and the San Antonio Valley south of Livermore. There’s tremendous diversity in the south Diablo Range.”

Further north, the geography and shallow soils of Mount Diablo make it a year-round hotspot for wildflowers. “You can see 100 to 150 different kinds of flowers during the season, and it’s already started,” Adams said.
