Himalayan stellera (Stellera chamaejasme)

Dmitry Poltavsky - Stellera chamaejasme

Stellera chamaejasme is a perennial weed with a wide geographic range that is found from the Altai of eastern Russia, northern China and Mongolia southwards as far as the western Himalayas of the Qinghai-Tibet and Yungui Plateaus. The best known form has pale pink tubes and white lobes, but in China and Mongolia at least the flowers can be entirely rich yellow. The root is poisonous.
