These plants are native to a broad area spanning from the Mediterranean region to Asia. Nerium species are notable for their striking flowers and are widely cultivated as ornamental plants in gardens and parks around the world. However, they are also known for being highly toxic to humans and animals if ingested.<br />
<br />
== Description ==<br />
Nerium plants are evergreen [[shrubs]] or small [[trees]], growing to 2–6 m tall. Their leaves are lanceolate, dark green, and arranged in whorls of three. The flowers are showy, with a five-lobed corolla, typically white, pink, or red, and are produced in dense clusters. The fruit is a long, narrow pair of follicles, which splits open at maturity to release numerous downy seeds.<br />
<br />
== Toxicity ==<br />
All parts of the Nerium plant contain toxic compounds known as [[cardiac glycosides]], primarily oleandrin, which can cause severe illness or death if ingested. Symptoms of oleander poisoning include nausea, vomiting, diarrhea, irregular heart rate, and in severe cases, death. Due to its toxicity, caution is advised when planting Nerium in areas accessible to children and pets.<br />
<br />
== Cultivation and Uses ==<br />
Despite its toxicity, Nerium is widely cultivated for its attractive flowers and ability to thrive in poor soils and harsh climatic conditions. It is drought-tolerant and can be used in xeriscaping. The plant requires minimal maintenance once established and can be propagated from cuttings or seeds. However, it is susceptible to pests and diseases such as aphids, scale insects, and root rot.<br />
<br />
== Species ==<br />
The most well-known species within this genus is ''Nerium oleander'', commonly referred to as oleander. It is the only species currently classified in the genus, though there has been historical debate over the inclusion of other species.<br />
<br />
== In Culture ==<br />
Nerium oleander has been associated with various cultural and historical narratives. It is mentioned in ancient texts and has been used in traditional medicine, despite its toxic properties. In some cultures, it symbolizes caution or danger due to its toxicity, while in others, it is admired for its beauty and resilience.<br />
<br />
== Conservation ==<br />
While ''Nerium oleander'' is not currently considered at risk of extinction, its natural habitats are threatened by urbanization and land-use change. Conservation efforts focus on preserving its native ecosystems and ensuring that its cultivation as an ornamental plant does not lead to ecological imbalances.<br />
