Lycianthes rantonnetii

Lycianthes rantonnetii, the blue potato bush or Paraguay nightshade,[1] is a species of flowering plant in the nightshade family Solanaceae, native to South America.[2] Growing to about 6 ft (1.8 m) tall and broad,[1] it is a rounded evergreen shrub with a somewhat lax habit. A profusion of trumpet-shaped, bright blue-purple flowers with a prominent yellow eye appear in summer, followed by red berries. It is widely cultivated and may be hardy in mild or coastal areas. Alternatively it can be grown in a container and brought under cover in winter. It requires a sheltered location in full sun.[3] Though related to food plants like the potato and tomato, all parts of the plant are considered toxic to humans.
