Cascabela thevetia aka Luckynut

Cascabela thevetia (synonym: Thevetia peruviana) is a poisonous evergreen tropical shrub or small tree native to Mexico, Central America and the West Indies. It is closely related to Nerium oleander, or oleander, and has many similarities to it, including alternate bright green leaves, milky sap when cut, and fragrant funnel-shaped yellow (or apricot) flowers in few-flowered terminal clusters, although yellow oleander has yellow flowers. The plant is widely cultivated as an ornamental, and in the West Indies it is known as "lucky nut". Smoke from burning plant material can also be toxic and the plant stems exude a milky sap when cut, so all parts of the plant should be handled with care. The genus name, Cascabela, comes from the Spanish word cascabela, meaning "small bell", in reference to the shape of the flower, while the specific epithet, peruviana, is a tribute to a French monk by the name of André Thevet, who traveled in Brazil and Guiana.
