Thevetia (Cascabela thevetia)

Thevetia, commonly known as Yellow Oleander, is an evergreen shrub or small tree from the Apocynaceae family, admired for its dense foliage and vibrant, trumpet-shaped flowers. Native to Central and South America, it is now widely cultivated in tropical and subtropical regions for ornamental purposes. The plant typically grows between 60 cm to 120 cm in height and has glossy, dark green, lance-shaped leaves. Its striking flowers bloom in clusters and come in shades of yellow, pink, or white, offering continuous color throughout the year. Thevetia also produces small, fleshy fruits that mature from green to yellow or orange.

Note: All parts of the Thevetia plant are highly toxic due to the presence of cardiac glycosides, so care should be taken to keep it away from children and pets.
