Cascabela thevetioides, commonly known as Yellow Oleander, is an evergreen shrub or small tree native to the dry regions of Central America and northern South America. It typically grows to a height of 8-15 feet (2.4-4.6 meters) and a similar width, featuring a rounded to irregular crown. The plant is notable for its glossy, lance-shaped leaves and its tubular, yellow to peach-colored flowers that bloom in summer and fall, providing a long-lasting and showy display. The fruit is a paired samara, but it is not particularly ornamental. Yellow Oleander is appreciated for its drought tolerance and its vibrant, fragrant flowers which can enhance sensory gardens.

In cultivation, Yellow Oleander is used for ornamental purposes in tropical and subtropical landscapes, often as a hedge, screen, or accent plant. It thrives in full sun to part shade and requires low to medium amounts of water once established, making it suitable for xeriscaping. It prefers well-drained soils and can tolerate a range of soil types, from sandy to loamy. Gardeners should be aware that all parts of the plant are highly toxic if ingested, and it can be invasive in suitable climates. Care should be taken to plant it away from areas frequented by children and pets.CC BY-SA 4.0
