Cascabela thevetia

Cascabela thevetia (syn: Thevetia peruviana) is a poisonous plant of central and southern Mexico and Central America. It is a relative of Nerium oleander, giving it a common name yellow oleander, and is also called lucky nut in the West Indies.
C. thevetia is an evergreen tropical shrub or small tree. Its leaves are willow-like, linear-lanceolate, and glossy green in color. They are covered in waxy coating to reduce water loss (typical of oleanders). Its stem is green turning silver/gray as it ages.
Flowers bloom from summer to fall. The long funnel-shaped sometimes-fragrant yellow (less commonly apricot, sometimes white) flowers are in few-flowered terminal clusters. Its fruit is deep red-black in color encasing a large seed that bears some resemblance to a 'Chinese lucky nut.'
