올레안더, known as Nerium oleander, is a flowering shrub native to the Mediterranean region. It is popular for its beautiful, fragrant flowers that come in various colors, including pink, white, and red. The plant thrives in warm climates and is often used in gardens and landscaping due to its hardiness and low maintenance requirements. Despite its attractive appearance, 올레안더 is highly toxic if ingested. All parts of the plant contain compounds that can cause serious health issues in humans and animals. Therefore, caution is advised when planting it in areas accessible to pets and children.
