Golden Spiderflower: A Bright Native Annual for Western Gardens
If you’re looking to add a splash of sunshine to your western garden while supporting local wildlife, the golden spiderflower (Cleome platycarpa) might just be the perfect native annual you’ve been searching for. This cheerful wildflower brings both beauty and ecological value to landscapes across the American West.


What Makes Golden Spiderflower Special?
Golden spiderflower is a true native of the western United States, naturally occurring in California, Idaho, Nevada, and Oregon. As an annual forb, this herbaceous plant completes its entire life cycle in one growing season, making it a dynamic addition to gardens that change from year to year.
What sets this plant apart is its rapid growth rate and cheerful yellow blooms that appear in late spring and continue through summer. Reaching about 2 feet in height, golden spiderflower creates an upright, single-crowned form that adds vertical interest to garden beds without overwhelming smaller companions.
Garden Design and Landscape Role
Golden spiderflower shines in several garden settings:
- Native plant gardens: Perfect for authentic western landscapes
- Wildflower meadows: Adds bright color to naturalized areas
- Xeriscape gardens: Thrives with minimal water once established
- Pollinator gardens: Supports beneficial insects with its blooms
Its moderate spread rate and high seed production make it excellent for filling in gaps naturally, though it won’t become aggressive or take over your garden.
Growing Conditions and Care
One of the best things about golden spiderflower is how easy it is to please. This drought-tolerant native prefers:
- Soil: Medium to fine-textured soils with good drainage
- pH: Adaptable to a wide range (6.5-8.9)
- Sun exposure: Full sun (shade intolerant)
- Water needs: Medium moisture use with good drought tolerance
- Temperature: Needs at least 130 frost-free days
The plant shows high tolerance for alkaline soils and moderate salt tolerance, making it suitable for challenging western growing conditions.
Planting and Propagation
Growing golden spiderflower from seed is straightforward and rewarding:
- Seeding: Direct sow seeds in spring after last frost
- Germination: Seeds have high vigor and germinate readily
- Timing: Plant when soil temperatures reach at least 52°F
- Spacing: Allow room for 2-foot mature height
- Maintenance: Very low once established
With approximately 200,000 seeds per pound, a little goes a long way! The plants readily self-seed, so you may find volunteers returning each year.
Wildlife and Pollinator Benefits
As a native wildflower with conspicuous yellow blooms, golden spiderflower likely provides nectar and pollen for native bees, butterflies, and other beneficial insects. The abundant seed production also offers potential food sources for birds later in the season.
Why Choose Golden Spiderflower?
This native annual offers several compelling reasons to include it in your garden:
- Supports local ecosystems and wildlife
- Requires minimal water and care
- Adds bright, cheerful color from late spring through summer
- Adapts to challenging soil conditions
- Self-seeds for natural garden renewal
While golden spiderflower may not be commercially available at every nursery, sourcing seeds from native plant societies or specialty suppliers ensures you’re getting authentic regional genetics. This small investment in native flora pays dividends in creating resilient, beautiful landscapes that celebrate the natural heritage of the American West.
Whether you’re creating a new wildflower meadow or adding native touches to existing beds, golden spiderflower brings the perfect combination of low-maintenance beauty and ecological value to western gardens.
