Nerium oleander is a shrub native to the Mediterranean coast and Asia, and it is popular in gardens due to its beautiful flowers and fragrant scent. Below is information regarding the growth characteristics, propagation methods, cultivation methods, garden uses, and pest and disease control methods for oleander.

Growth Characteristics
- Climate and Environment: Nerium oleander prefers a warm climate and thrives even in hot and dry conditions. It is somewhat sensitive to cold, and delicate buds may be damaged during the winter.
- Soil: It prefers well-drained sandy soil but adapts well to various soil types.
- Sunlight: It grows best in sunny locations. While it can grow in partial shade, it tends to produce fewer flowers.

Propagation Methods
