Plagiorhegma dubium
This plant is kept in the atlas for identification and safety, not for use. Read the safety notes below before handling it, and keep it away from children, cats, and food.
Plagiorhegma dubium is best known and loved as an ornamental, one of the first woodland plants to bloom each year, its lavender cup-shaped flowers opening before the paired leaves have even fully unfurled. It shares its old genus name, Jeffersonia, with its North American cousin Jeffersonia diphylla, which was documented in early American folk medicine, but the Asian species itself has little recorded history of medicinal use outside its native range. Gardeners have prized it for centuries in East Asian woodland plantings for its quiet, fleeting beauty rather than for any household remedy.
Safety.
No established history of safe internal use, and it belongs to the barberry family, which includes plants with concerning alkaloid content, so it shouldn't be eaten and should be kept away from children and pets.
