Oregon Fetid Adderstongue: A Quirky Native Wildflower for Shade Gardens
With a name like fetid adderstongue, you might wonder if this little woodland wildflower is worth a second look. But don’t let the unusual moniker fool you – Oregon fetid adderstongue (Scoliopus hallii) is a fascinating native perennial that brings early spring interest to Pacific Northwest shade gardens, even if it does come with a slightly funky fragrance.
What Makes Oregon Fetid Adderstongue Special
This charming little forb is a true Oregon original, found nowhere else in the world except in the cool, moist forests of the Pacific Northwest. As a perennial wildflower, it returns year after year, emerging in late winter to early spring when most other plants are still sleeping.
