Cushenbury Buckwheat: A Rare California Native Worth Protecting
Meet the Cushenbury buckwheat (Eriogonum ovalifolium var. vineum), a remarkable little perennial that’s as special as it is scarce. This California native represents one of nature’s more exclusive offerings – and that exclusivity comes with both wonder and responsibility.
What Makes Cushenbury Buckwheat Special?
The Cushenbury buckwheat is a native perennial forb, meaning it’s an herbaceous plant that lacks woody tissue above ground but returns year after year. Unlike shrubs or trees, this charming plant keeps its growing points at or below soil level, making it well-adapted to harsh conditions.
This variety is also known scientifically as Eriogonum ovalifolium Nutt. ssp. vineum (Small) S. Stokes, reflecting its classification as a distinctive variety within the broader oval-leaf buckwheat complex.
Where Does It Call Home?
Cushenbury buckwheat is exclusively native to California, representing the Golden State’s incredible botanical diversity. As a plant native to the lower 48 states, it has evolved specifically to thrive in California’s unique climate and soil conditions.
A Word of Caution: This Plant is Endangered
Before we dive into growing tips, here’s something crucial to know: Cushenbury buckwheat is listed as Endangered in the United States, with a Global Conservation Status of S5T1. This means it’s at serious risk of extinction in the wild.
If you’re interested in growing this remarkable native, please ensure you source it only from reputable nurseries that propagate plants responsibly – never collect from wild populations. Better yet, consider supporting conservation efforts for this species while exploring other buckwheat varieties that aren’t at risk.
