Skunkbush: A Humble Native Annual Worth Knowing
Don’t let the name fool you – skunkbush (Navarretia squarrosa) might not win any beauty contests, but this unassuming little native annual has more to offer than meets the eye. While it may not be the showstopper of your garden, this modest wildflower plays an important role in supporting local ecosystems and can be a valuable addition to naturalistic landscapes.




What is Skunkbush?
Skunkbush is a native North American annual forb, meaning it’s a soft-stemmed herbaceous plant that completes its entire life cycle in one growing season. Also known by its botanical name Navarretia squarrosa (formerly classified as Gilia squarrosa), this humble plant belongs to the phlox family and produces small, delicate flowers that may be easily overlooked but serve an important ecological purpose.
Where Does Skunkbush Grow Naturally?
This adaptable native species has a broad distribution across western North America, naturally occurring in British Columbia, California, Montana, Oregon, Washington, and even Pennsylvania. Its widespread presence across such diverse climates speaks to its resilience and adaptability, making it suitable for USDA hardiness zones 7-10.
Why Consider Skunkbush for Your Garden?
While skunkbush may not be the most ornamental choice, there are several compelling reasons to include it in your native plant palette:
- True native credentials: Supporting plants indigenous to North America helps maintain local biodiversity
- Pollinator support: The small flowers provide nectar for native bees and other beneficial insects
- Low maintenance: As an annual adapted to local conditions, it requires minimal care once established
- Ecological authenticity: Adds genuine native character to wildflower meadows and naturalized areas
- Versatile growing conditions: Thrives in the well-drained, sunny spots where many plants struggle
Where Skunkbush Fits in Your Landscape
Skunkbush works best in informal, naturalistic settings rather than formal garden beds. Consider incorporating it into:
- Native plant gardens focused on local flora
- Wildflower meadows and prairie restorations
- Areas where you want to encourage beneficial insects
- Slopes or areas with poor soil that need stabilization
- Transition zones between cultivated and wild areas
Its facultative upland status means it typically prefers non-wetland conditions but can tolerate occasional moisture, making it adaptable to various garden situations.
Growing Skunkbush Successfully
The beauty of growing native annuals like skunkbush lies in their simplicity. Here’s how to give them the best start:
Planting Conditions
- Sunlight: Full sun to partial shade
- Soil: Well-draining soil; tolerates poor, sandy, or rocky conditions
- Water: Drought tolerant once established; avoid overwatering
- pH: Adaptable to various soil pH levels
Planting and Care Tips
- Direct seed in fall or early spring when temperatures are cool
- Scatter seeds on prepared soil and lightly rake in
- Water gently until germination occurs
- Once established, minimal watering is needed
- Allow plants to self-seed for naturalized colonies
- No fertilization necessary – natives prefer lean soils
Setting Realistic Expectations
Let’s be honest – skunkbush isn’t going to create dramatic garden focal points or generate compliments from neighbors. Its flowers are small and its overall appearance is rather modest. However, if you’re building a garden that prioritizes ecological function over flashy aesthetics, skunkbush earns its place through quiet contributions to biodiversity.
Think of it as a supporting player rather than the star of your garden show. It works best when combined with other native species that can provide more visual interest while skunkbush does its important work behind the scenes.
The Bottom Line
Skunkbush represents the understated beauty of native gardening – it may not demand attention, but it delivers authentic ecological value. If you’re committed to supporting native biodiversity and don’t mind trading some ornamental pizzazz for genuine conservation benefits, this humble annual deserves consideration. Just remember to manage expectations and pair it with more visually striking native companions for a balanced, beautiful, and beneficial garden.
