Fetid Adderstongue: A Quirky Native Gem for Shade Gardens
If you’re looking for a conversation starter in your shade garden, look no further than the fetid adderstongue (Scoliopus). Don’t let the unflattering name fool you – this unique Pacific Northwest native brings an otherworldly charm to woodland gardens that’s hard to replicate with any other plant.
What Makes Fetid Adderstongue Special?
Fetid adderstongue is a perennial forb that’s as unusual as its name suggests. This herbaceous plant lacks woody tissue and dies back to underground bulbs each winter, emerging fresh each spring with distinctive mottled leaves and twisted, alien-like flowers.
The flowers are truly the star of the show – small but striking, with purple-brown petals that twist and curve in fascinating spirals. While the blooms may emit a slightly unpleasant odor (hence the fetid in the name), this unique characteristic serves an important ecological purpose by attracting specific pollinators like flies and fungus gnats.
Where Does It Grow Naturally?
As a native plant of the lower 48 states, fetid adderstongue calls the Pacific coast home. You’ll find this fascinating plant growing naturally in the forests of California and Oregon, where it thrives in the cool, moist conditions of the coastal and mountain woodlands.
Why Plant Fetid Adderstongue in Your Garden?
There are several compelling reasons to consider adding this native beauty to your landscape:
- Supports native ecosystems: As a regional native, it provides food and habitat for local wildlife
- Unique aesthetic appeal: The mottled leaves and twisted flowers create visual interest unlike any other garden plant
- Low maintenance: Once established, it requires minimal care
- Shade tolerance: Perfect for those challenging deep shade areas where few plants thrive
- Pollinator support: Attracts specialized native pollinators
Perfect Garden Settings
Fetid adderstongue shines in woodland and shade gardens where its subtle beauty can be appreciated up close. It’s an excellent choice for:
- Native plant gardens
- Woodland understory plantings
- Shade borders and naturalized areas
- Rock gardens with dappled shade
This plant works beautifully as a specimen plant where visitors can discover its unique flowers, or massed in drifts for a more naturalistic effect.
Growing Conditions and Care
Success with fetid adderstongue comes down to mimicking its natural forest habitat:
- Light: Deep to partial shade – avoid direct sunlight
- Soil: Moist, well-draining soil rich in organic matter
- Water: Consistent moisture, especially during growing season
- Temperature: Cool conditions; thrives in USDA zones 7-9
Planting and Care Tips
Getting started with fetid adderstongue is straightforward once you understand its needs:
- Planting time: Plant bulbs in fall for spring emergence
- Soil preparation: Amend heavy soils with compost for better drainage
- Spacing: Allow 6-8 inches between plants
- Mulching: Apply organic mulch to retain moisture and suppress weeds

Is Fetid Adderstongue Right for Your Garden?
Consider fetid adderstongue if you’re passionate about native plants, enjoy unique and unusual specimens, and have the right growing conditions. This plant is perfect for gardeners who appreciate subtle beauty and want to support local ecosystems.
However, it might not be the best choice if you’re looking for showy, long-lasting blooms or need plants for sunny locations. The flowers are small and brief, and the overall growth habit is quite modest.
For Pacific Northwest gardeners with woodland conditions, fetid adderstongue offers a chance to grow something truly special – a native plant that tells the story of your local landscape while adding an element of mystery and intrigue to your shade garden.
