Oleander (Nerium oleander) is a beautiful and versatile flowering shrub known for its attractive flowers and evergreen foliage. Here's some information about Oleander:

1. Appearance: Oleander is a dense, multi-branched shrub that can grow up to 6 to 12 feet (1.8 to 3.6 meters) tall. It has long, lance-shaped leaves that are leathery and glossy, arranged in opposite pairs along the stems. The flowers are showy and come in a variety of colors, including white, pink, red, and yellow. They are funnel-shaped with five petals and are often fragrant.

2. Cultivation: Oleander is native to the Mediterranean region but is now widely cultivated in various parts of the world. It is valued for its ability to tolerate a wide range of growing conditions, including high heat, drought, and poor soil. It prefers full sun but can tolerate partial shade. Oleander can be grown in containers or in the ground as a specimen plant, hedge, or screen.

3. Toxicity: It's important to note that all parts of the Oleander plant, including the leaves, flowers, and sap, contain toxic compounds. Ingesting the plant can be harmful and even fatal, so caution should be exercised, especially around children and pets. It is advisable to handle Oleander with gloves and wash hands thoroughly after any contact.

4. Flowering Season: Oleander typically blooms in late spring through summer, producing abundant clusters of flowers. The flowers are long-lasting and can add vibrant color to landscapes and gardens.

5. Pruning and Maintenance: Pruning Oleander helps maintain its shape and encourages bushier growth. It is best to prune in late winter or early spring before new growth appears. Deadheading, or removing spent flowers, can promote continued blooming. Oleander has a natural tendency to produce suckers from the base, which can be removed to control the plant's growth and maintain a tidy appearance.

6. Cultural Significance: Oleander has a long history of cultural significance. It is associated with various meanings and symbols, including love, beauty, and femininity. In some cultures, it is considered a symbol of protection and good luck.

While Oleander is a stunning and hardy shrub, it's important to be aware of its toxic nature. Proper precautions should be taken when handling and growing this plant. With proper care and attention, Oleander can be a striking addition to gardens and landscapes, offering beautiful flowers and evergreen foliage.
