(The plant has potential to bloom seasonal flower. But currently is without flower.)
Nerium oleander, most commonly known as nerium or oleander, is a shrub or small tree in the dogbane family Apocynaceae, cultivated worldwide in temperate and subtropical areas as an ornamental and landscaping plant. It is the only species currently classified in the genus Nerium.
Although the shrubs are drought-tolerant, they look their best when they are watered during dry spells. However, take care not to over water them. Yellowing leaves indicate that the plant is getting too much water. If the soil is poor, feed the plant lightly with a balanced fertilizer during its first spring.
