If you’re looking to add some delicate charm to your woodland garden, forest scurfpea (Rupertia physodes) might just be the perfect native wildflower you’ve been searching for. This unassuming perennial brings subtle beauty and ecological value to shaded spaces across the Pacific Northwest.
What is Forest Scurfpea?
Forest scurfpea is a native North American perennial forb that belongs to the pea family. As a herbaceous plant, it lacks woody stems but returns year after year from its root system. You might also encounter this plant listed under its synonym, Psoralea physodes, in older gardening references.
What makes forest scurfpea particularly interesting is its distinctive inflated seed pods that give it part of its scientific name physodes, which refers to these balloon-like structures. The small, delicate flowers are typically white to pale pink and arranged in loose clusters, creating a gentle woodland display.
Where Does Forest Scurfpea Grow Naturally?
This native beauty calls the Pacific Northwest home, naturally occurring across British Columbia, California, Idaho, Oregon, and Washington. It’s adapted to the understory conditions of the region’s forests, making it an excellent choice for gardeners wanting to recreate natural woodland ecosystems.
