Exploring the Beauty of California Native Wildflowers

California Poppy

The state flower of California, the California poppy (Eschscholzia californica), is perhaps the most iconic wildflower of the state.

These golden-orange blooms with delicate petals brighten up any sunny spot in the garden in winter and spring.

California poppies thrive in well-drained soils and even poor, sandy soils.

Matilija Poppy

With flowers the size of dinner plates in white, pink, and yellow, the giant matilija poppy (Romneya coulteri) makes an unforgettable addition to a native garden.

Reaching up to 7 feet tall when in bloom, this perennial wildflower prefers partly sunny spots and is drought tolerant once established.

The large rhizomes spread freely, so give it plenty of room.

Fuchsia-Flowered Gooseberry

A California native shrub suited to informal hedges and screens, fuchsia-flowered gooseberry (Ribes speciosum) bursts forth with drooping clusters of vibrant red flowers.

This easy-going, low-maintenance shrub grows 5-6 feet tall and wide in part shade/sun, enriching the soil and attracting wildlife.

Prune every few years to shape and stimulate new growth.

Showy Penstemon

Adding fiery color to any garden is showy penstemon (Penstemon spectabilis), which sends up spikes of bright red-orange tubular flowers in late spring.

These easy-care perennials reach 3 feet tall and spread slowly, preferring lean, fast-draining soil and full sun exposure.

Deadheading spent blooms promotes waves of rebloom.

California Lilac

With sweetly fragrant purple flower clusters and attractive gray-green foliage, California lilac (Ceanothus spp.) is a garden standout for much of spring.

These versatile evergreen shrubs thrive in full sun and adapt to most soil types, including clay.

Prune old branches right after flowering for the best appearance and bloom performance.

Douglas Iris

A western native treasure, Douglas iris (Iris douglasiana), lights up dry slopes and wild areas with blooms in shades of purple, blue, pink, white, and maroon.

This hardy perennial reaches 1-2 feet tall and does best in well-drained, even poor-quality soil, with occasional summer watering.

Good for borders and cottage gardens.

Golden Eardrops

A jewel-like ground cover for sunny, hot slopes is golden eardrops (Ehrendorferia chrysantha).

Starting in mid-spring, brilliant golden flower clusters dangle from wispy trailing stems reaching 2 feet long.

Mix with other natives and grasses for gorgeous spring and summer colors. Needs good drainage but tolerates some summer watering once established.

Chinese Houses

A charming and durable annual wildflower that self-sows freely is Chinese houses (Collinsia heterophylla).

Planted in fall or winter, it sends up whorls of purple and white pea-like blossoms on tall, leafy spires come springtime.

These cottage garden favorites reach 3 feet tall and reseed readily in prepared garden beds. Thin unwanted seedlings to control spread.

Tidy Tips

A standout wildflower for hot, dry slopes is tidy tips (Layia platyglossa).

The daisy-like yellow blooms with neat white tips blanket the foliage in spring and early summer.

These short-lived perennials reach 1 foot tall. Let them self-seed for recurring waves of cheerful color where they are happy.

Farewell-to-Spring

A fitting name for a late spring bloomer is farewell-to-spring (Clarkia amoena).

Showy bowl-shaped blooms in shades of pink and purple adorn leafy upright stems that can reach 3 feet tall in garden conditions.

These hardy annuals grow well in average soil and full sun exposure. Save seeds for fall replanting.

Blue-Eyed Grass

A sweet addition to any meadow or garden is blue-eyed grass (Sisyrinchium bellum).

These delicate perennials produce cheery purple-blue flowers with bright golden centers reminiscent of their namesake. 

The narrow, grass-like foliage forms an attractive mound reaching 6-8 inches tall. Blue-eyed grass thrives in light shade and evenly moist soils.

California Buttercup

Blanketing the landscape in vibrant gold is the California buttercup (Ranunculus californicus).

This short-lived perennial emerges with toothed foliage followed by abundant shiny yellow blooms over 3 inches wide. 

California buttercups spread readily from seed in meadows, grasslands, and open forests, reaching 8 inches tall. They need good drainage and do just fine in poor soils.

Purple Owl’s Clover

Adding a pop of color to spring lawns and meadows is purple owls’ clover (Castilleja exserta). 

The inch-long scarlet red flowers stand out brightly against the lush green foliage from March to May, reaching 1 foot tall when in bloom. 

These short-lived perennials grow quickly from directly sown seed and self-sown once established. No need to prune or fuss over them!

California Golden Violet

A harbinger of spring is the California golden violet (Viola pedunculata), which carpets wooded areas with charming yellow flowers. 

The heart-shaped leaves form a lush, deep green backdrop to the half-inch blooms that peak from March to June. 

These 5-inch tall perennials grow best in dappled or light shade with rich, moist soil. Give them time to establish, and they will steadily spread.

Blue Dick

With electric blue spherical flower clusters, blue dick (Dichelostemma capitatum) is sure to catch your eye when in bloom. 

Slender arched foliage gives rise to these eye-catching blooms on 2-foot tall stems during spring and early summer. 

Blue dicks thrive with other wildflowers and grasses in open sunny areas with well-drained soil. The bulbs go dormant after flowering.
