I’M NOT SHOUTING!
This is just how I talk this time of year when the WILDFLOWER SEASON IS UPON US! Ok, maybe I am shouting a little. Sorry, I’m just really excited.
I get this way around the spring bloom and spontaneously start shouting with excitement. And for good reason — it’s that time of year again to hit the trails (you gotta try our Wildflower Guide) in search of nature’s picturesque botanical arrangements.
People get feverish about California’s wildflower season every year, clamoring for the chance to witness our open spaces at the peak of their abundance.
What’s funny though is that despite my enthusiasm and diehard intentions of becoming a top-tier nature nerd, I still can’t seem to remember the names of all but a few of California’s wildflowers. The wannabe plant geek in me just can’t seem to get it, even after the superblooms of the past few years and ample opportunities to refine this part of my naturalistic repertoire.
So, I’m sticking to the fundamentals. If you’re like me and struggle to remember plant names (as well as where you put your car keys, wallet and phone), then I suggest you do the same. Below, you’ll find 10 of the most common of northern California wildflowers, some fun facts about their natural history and where to find them in our local open spaces. These are the plants I’m committed to remembering — the wildflowers that we’re most likely to see on the trail.
Here we go:
1. Douglas iris
Iris douglasiana
In bloom: February – June
A great place to find them: Coal Creek Open Space Preserve
Fun fact: Despite the tremendous labor involved, the Indigenous communities in California used this plant’s strong petals to weave fishing nets and rope. They also used (and some still use) the dried roots as a diuretic.
Find more information at Calflora.
2. Sky Lupine
Lupinus nanus
In bloom: March – May
A great place to find them: Russian Ridge Open Space Preserve
Fun fact: Look for their soft grey-green leaves which are coated in silvery hairs. They are one of the most abundant flowers in our local grasslands.
Find more information at Calflora.
3. Sticky monkey flower
Diplacus aurantiacus
In bloom: March – May
A great place to find them: Rancho Corral de Tierra
Fun fact: An important host for the larvae of the variable checker-spot butterfly, this plant’s heavy resin helps retain water in dry environments.
Find more information at Calflora.
4. Indian paintbrush
Castilleja affinis
In bloom: March – May
A great place to find them: Sierra Azul Open Space Preserve
Fun fact: This plant can produce its own food, but if malnourished, it will feed off the roots of nearby plants. It blooms in spring and often holds its color throughout the summer.
Find more information at Calflora.
5. Tidy Tips
Layia platyglossa
In bloom: March – July
A great place to find them: Calero County Park
Fun fact: Often used in native grassland restoration efforts to help attract local pollinators, this plant’s seeds are also a good food source for birds.
Find more information at Calflora.
6. Redwood sorrel
Oxalis oregana
In bloom: February – July
A great place to find them: Purisima Creek Open Space Preserve
Fun fact:These plants are well adapted to life in the shade; when direct sunlight strikes the leaves, they fold toward the ground and, when the shade returns, the leaves reopen.
Find more information at Calflora.
7. Miner’s lettuce
Claytonia perfoliata
In bloom: February – May
A great place to find them: Thornewood Open Space Preserve
Fun fact: True to its name, this plant was a valued food source for Gold Rush-era miners when food supplies were scarce. The taste is similar to spinach but please don’t harvest plants from public land.
Find more information at Calflora.
8. Yarrow
Achillea millefolium
In bloom: April – August
A great place to find them: Pearson-Arastradero Preserve
Fun fact: Several nesting birds, including the common starling, use yarrow to line their nests as its oils repel pesky insects like mites and mosquitos.
Find more information at Calflora.
9. California Fuchsia
Epilobium canum
In bloom: August – October
A great place to find them: Russian Ridge Open Space Preserve
Fun fact: A favorite among hummingbirds, this flower blooms in the fall before the bird’s winter migration, a unique trait among wildflowers.
Find more information at Calflora.
10. California poppies
Eschscholzia californica
In bloom: February – September
A great place to find them: Edgewood Park and Natural Preserve
Fun facts: We can’t forget the state flower of California, which can be seen in brilliant shades of red, orange and yellow. And don’t forget to celebrate California Poppy Day on April 6.
