Native to Western Australia, and close to the southwest coast in particular, common brown pea is a small shrub reaching ~1.2m (4 ft.) in height. It is typically associated with sandy soils.
The Friends of Queens Park Bushland explain the derivation of the scientific name in their brief article on Bossiaea eriocarpa. The species seems to be uncommon, if not outright rare, in cultivation (especially outside of Australia). Perhaps it is because some describe the shrub as “straggly”. Other photographs of Bossiaea eriocarpa reveal that there is a diversity of floral colour form; my preference is the one shared today by Lorraine.
Bossiaea contains somewhere around 50-70 species, with the exact number shifting with taxonomic viewpoint. All species are native and endemic to Australia.
On a different topic, something that may interest a few readers: California’s Rancho Santa Ana Botanic Garden is running a Kickstarter campaign to fund a new exhibition on the various armatures of plants, like spines, prickles, and thorns. Visit Game of Thorns for more!
