Oleander is a flowering shrub known for its beautiful, fragrant blooms, which can be pink, white, or yellow. It thrives in warm climates and is often used in gardens and landscaping due to its hardiness and ability to tolerate drought. However, all parts of the oleander plant are toxic if ingested, containing compounds that can cause serious health issues. Despite its beauty, caution is advised when planting oleander, especially in areas where pets or children may be present.
