Nicotiana glauca

Native to central South America, it forms a slender, branching shrub or small tree. It commonly reaches about nine feet tall, although larger wild plants can exceed twenty feet. Long yellow tubular flowers hang in loose clusters at the ends of shoots. Its leaves are smooth and blue-green. All parts are highly poisonous if eaten. It has become invasive in California, where dense stands can displace native vegetation. It belongs to the nightshade family, Solanaceae. Photographed in Colombia.
