Oleander (Nerium oleander)

Images are for reference only and should not be used as the sole method of identification. Always confirm identification with a qualified source.

Oleander (Nerium oleander) is an evergreen shrub in the Apocynaceae family native to the Mediterranean region and parts of southwest Asia. It bears narrow leathery leaves and clusters of pink, white, red, or yellow flowers, and although it has appeared in historical records, all parts of the plant are considered highly toxic.

Oleander is far better known as an ornamental landscape shrub than as a practical herb. Because of its poisonous nature, it should not be used in home remedies, teas, or casual preparations, and its presence on botanical and historical herb lists is best understood as a matter of plant history rather than safe domestic use.

Botanical Study Only

Oleander is best treated as a plant for identification, ornamental cultivation, and historical reference rather than domestic herbal making.

Part of the plant used: No home-use plant part is recommended

Growing Oleander

Oleander is a tough evergreen shrub widely grown as an ornamental in warm regions, where it tolerates heat, drought, and poor soils once established.

Prefers full sun
Grows in well-drained soil and tolerates dry conditions
Best suited to USDA zones 8-11
Commonly grown in warm coastal and southern parts of the United States
Often used in landscapes, medians, and hedging in frost-free regions

Oleander can be easy to grow in the right climate, but it should be planted thoughtfully because all parts of the shrub are poisonous. Gardeners should use gloves when pruning and keep it away from children, pets, and livestock.

Safety Considerations

Oleander is highly poisonous and should not be used in casual home herbal preparations.

However:

All parts of oleander are toxic, including the leaves, flowers, stems, sap, and smoke from burning prunings.
Accidental ingestion can be very dangerous for people, pets, and livestock.
Skin contact with the sap may irritate some individuals.
Oleander should never be used in self-made teas, tinctures, or internal remedies.
Gardeners should use caution when pruning and should wash hands after handling the plant.
Always seek urgent professional help in cases of suspected ingestion or poisoning.
Always consult a qualified professional before using herbs for health purposes.
