California's Wildflowers are Back!

You may have noticed. Since the end of the drought a couple years ago, each rainy season has resulted in an ever increasing, more vibrant springs. Heavy rains contribute to wildflower blooms because they trigger germination of dormant seeds and provide the necessary moisture for growth. Many annual wildflowers, particularly in arid or semi-arid regions, rely on specific rain events to wash away protective coatings from their seeds, allowing them to sprout and grow. A combination of sufficient rainfall, adequate sunlight, and suitable temperatures are crucial for successful wildflower expansion, including the formation of blooms and the dispersal of seeds.

Wildflower Season is Upon Us!

I’m seeing the spring blooms everywhere, and I see more this year than I saw last year. Nature’s picturesque arrangement is plastered on the hillsides of the 580 freeway along the Dublin grade between Pleasanton and Castro Valley at Dublin Hills Regional Park. I see California Poppies litter the hills of the Lake Chabot area. Mission Peak in Fremont has a vibrant display of wildflowers too. And while there isn't a specific "wildflower trail," many of the trails in the area, like the Mission Peak Trail and Ohlone College Trail, offer opportunities to admire various wildflowers along the way.

The Tri-Valley area has also experienced an explosion of wildflower growth throughout regional parks and open space areas, making for an extra colorful spring. There are several places locally to both enjoy the outdoors and see some wildflowers.

Las Trampas Regional Park offers visitors far-reaching 360-degree views of the surrounding valleys and thousands of acres of open spaces. In addition to being home to the O’Neill National Historic Site, an abundance of plant and wildlife dwell in this preserve. Each spring the park’s hillsides and canyons are carpeted with a variety of wildflowers. To see the blooms try taking Rocky Ridge View Trail, Las Trampas Ridge Trail, and Sycamore Trail.  Las Trampas Regional Park is also one of the most popular places in the Tri-Valley area to take your dog on off-leash hikes.

Mount Diablo State Park offers terrific views of the surrounding foothills. In addition to featuring panoramic views where wildflowers thrive, some of the plant species found here aren’t found anywhere else in the world. Wildflowers grow year-round in the park but those who are looking for colorful blooms should visit in spring where they are easily spotted alongside the winding roads that lead to the mountain’s summit. If you’re up for a hike visit the following trails: North Peak Trail, Mary Bowerman Trail, and Mitchell Canyon.

Del Valle Regional Park just south of Livermore surrounds Lake Del Valle. Like Anthony Chabot Regional Park, it’s a popular spot for hiking, mountain biking, horseback riding, boating, picnicking, and camping. The park’s rolling hills turn a gorgeous green and feature several pops of color each spring. Visitors seeking out wildflowers should visit the park between mid-February and mid-May.

Sunol Regional Wilderness is home to an expansive trail system, a variety of naturalist activities, and several picnic sites alongside the Alameda Creek. Visitors come to view wildlife and take in the scenery at Little Yosemite, a picturesque gorge located two miles upstream from the visitor center. Each spring, the hillsides of Sunol Regional Wilderness turn gold, yellow, and lavender with the growth of California poppies, lupines, and mustard.

There are Superblooms Throughout California

There’s no singular definition of a superbloom, but typically this term is used to describe large scale blooms of annual wildflower species that follow years of above average precipitation in arid habitats. One of the most impressive features of a superbloom is the drastic transition from a landscape with sparse vegetation to dense, colorful and vibrant masses of wildflowers. Some superblooms can be so extensive and dense that they can be seen from space.

Seeing a superbloom is an incredible and inspiring experience, and the heightened public interest they generate can help instill a deeper ethos of conservation in the general public. As habitat loss, climate change, the spread of invasive species and other factors continue to threaten California’s wildlands, broadening public support for plant conservation is more important than ever.

Popular Superbloom Spots Include:

Antelope Valley Poppy Preserve

Anza Borrego Desert State Park

Carrizo Plain National Monument

Death Valley National Park

Joshua Tree National Park

What if I want to plant some wildflowers myself?

Annual wildflowers are easy to grow and you can create a dense seasonal bloom. The best time to plant wildflower seeds is in the fall between October and November just before the first rain prior to the arrival of winter/cold temperatures. The early rain will aid in the germination and establishment of the seeds. Seeds will begin to germinate in the winter and bloom from early spring to summer.
