What is a shrub with glossy evergreen leaves and largefragrant white flowers?

Oleander is the name of one of many poisonous shrubs.

Specifically, oleander (Nerum oleander) can be a convenient choice for cultivators, gardeners, and landscapers. It grows in alkaline and poor soils. It has attractive parts and structure. It is drought- and salt-tolerant.

But all parts of an oleander shrub are poisonous. No amount of drying or processing changes that fact. Ingesting -- for example, chewing or saving foliage and twigs -- may dilate pupils, provoke diarrhea and nauseousness, and slow pulses. Additionally, burning any of the plant's parts will release toxic fumes.
