Lycianthes rantonnetii

Native from Bolivia through southern Brazil, Paraguay, and northeastern Argentina, this shrub can reach about ten feet tall, with an open or bushy form. Violet-blue to purple flowers have a pale yellow throat and conspicuous yellow anthers. The species inhabits seasonal forests and open areas and can flower for much of the year in suitable climates. All parts are poisonous if eaten and can cause severe digestive discomfort. Photographed in Colombia.
