Spring Flowers of the San Bernardino Mountains
Each of these flowers typically appears between April and May. Many are native, and all are beautiful in their own way.
1. California Poppy
California’s state flower, this bright orange poppy is a cheerful herald of spring. It tends to grow in clusters, creating a carpet of color that’s impossible to miss. You’ll often find it in open, disturbed soils—especially near trails or road edges in the San Bernardino Mountains.
- Status: Native
- Where to Find: Sunny hillsides, roadsides, and open meadows
- Sun Preference: Full sun
2. Lupine (Silver Lupine)
With tall spikes of purple-blue flowers, lupines add height and drama to the spring landscape. Their silver-green foliage makes them easy to spot even before blooming. Plus, they attract butterflies and native bees.
- Status: Native
- Where to Find: Rocky slopes, forest edges, and chaparral
- Sun Preference: Full sun to partial shade
3. Paintbrush (Desert or Indian Paintbrush)
These fiery red or orange blooms look like they’ve been dipped in paint. Paintbrush flowers are actually modified leaves (bracts), and they’re semi-parasitic—tapping into other plants for nutrients. Wild and a little rebellious, they’re a fan favorite among hikers.
- Status: Native
- Where to Find: Meadows, rocky ledges, and southern-facing slopes
- Sun Preference: Full sun
4. Spanish Broom (Spartium junceum)
For drivers coming up the mountain, this one is hard to miss—its tall, slender green stalks are topped with fragrant, bright yellow pea-like flowers that bloom in dense clusters. While beautiful, it is invasive to the region. Its golden blooms line mountain roads, offering a striking splash of color in the spring.
- Status: Non-native (Invasive)
- Where to Find: Roadsides, disturbed slopes, and open, sunny hillsides
- Sun Preference: Full sun
5. Mountain Garland (Clarkia unguiculata)
Adorned with chains of pink, magenta, or lavender blooms, this flower creates a garland-like effect in the spring breeze. This elegant wildflower is a California native and a favorite in native plant gardens. It often grows in clusters, adding delicate movement and romantic color to sun-drenched trails and meadows.
- Status: Native
- Where to Find: Foothills, open woodlands, and sunny slopes, especially at lower elevations
- Sun Preference: Full sun to partial shade
6. Western Thistle
With its spiky, silver-green foliage and bold magenta or lavender flower heads, Western Thistle is both tough and beautiful. Despite its prickly appearance, it plays a vital role in the ecosystem—providing nectar for bees, butterflies, and even hummingbirds. It adds both structure and color to spring landscapes in the San Bernardino Mountains.
- Status: Native
- Where to Find: Dry, open slopes, chaparral, and disturbed areas at various elevations
- Sun Preference: Full sun
7. Cryptantha (White Forget-Me-Nots)
These tiny, white, five-petaled flowers may be small, but they sparkle like snowflakes against the mountain soil. Often mistaken for true forget-me-nots, Cryptantha belongs to a different plant family but shares a similar charm. Look closely—its bristly stems and delicate blooms make it a quiet gem of the San Bernardino spring season.
- Status: Native
- Where to Find: Dry, rocky slopes, sandy soils, and open woodlands
- Sun Preference: Full sun
8. Sticky Monkeyflower (Diplacus aurantiacus)
This cheerful wildflower bursts with warm shades of orange, apricot, or salmon—standing out beautifully against rocky backdrops. The name “Sticky Monkeyflower” comes from the plant’s tacky, resinous leaves and the whimsical, monkey-face shape of its blossoms. It’s drought-tolerant and a vital nectar source for hummingbirds and butterflies.
- Status: Native
- Where to Find: Dry slopes, canyon walls, rocky outcrops, and chaparral areas
- Sun Preference: Full sun to partial shade
9. Golden Yarrow
Not a true yarrow, but it resembles one. Bright yellow clusters bloom from flat-topped stems and can handle heat and drought well. They’re a beacon of life in tough terrain. It’s a common flower found in the chaparral and mountain slopes of the San Bernardinos.
- Status: Native
- Where to Find: Open woodlands, grassy hillsides
- Sun Preference: Full sun
10. Common Sunflower (Helianthus annuus)
Tall and unmistakable, the Common Sunflower is a true symbol of summer on the horizon.

Their height and bright color make them easy to spot even from the car window as you explore the spring flowers in the San Bernardino Mountain roads.
- Status: Native
- Where to Find: Open meadows, disturbed soils, roadsides, and sunny clearings — often at lower elevations
