Nerium (Oleander)
Nerium oleander, commonly known as oleander, is an evergreen shrub or small tree prized for its vibrant blooms, hardiness, and versatility in landscaping. It belongs to the dogbane family, Apocynaceae, which includes periwinkle and plumeria. Native to the Mediterranean region and Asia, oleander thrives in warm climates and has become a popular ornamental plant worldwide.
Description: Oleander produces clusters of showy flowers in shades of pink, white, red, yellow, or peach. These blooms appear from late spring to early fall, filling gardens with color. The lance-shaped, leathery green leaves add year-round appeal, creating a lush, tropical look.
Growth Habit and Size: This fast-growing shrub can grow 6-20 feet (2-6 meters) tall and 4-10 feet (1.2-3 meters) wide. It has a dense growth habit, making it ideal for hedges, windbreaks, or privacy screens.
Hardiness and Adaptability: Oleander is remarkably adaptable, thriving in USDA zones 8-11. It tolerates heat, drought, and poor soils, including sandy and alkaline conditions. Its salt tolerance makes it a favorite for coastal gardens.
Toxicity: All parts of the plant—leaves, stems, flowers, and sap—are highly toxic to humans and animals if ingested. Proper precautions should be taken, especially in areas accessible to children and pets.
Uses: Oleander is often planted as a hedge, screen, or windbreak. Its colorful blooms also make it a popular choice for borders, containers, and public landscapes.
