Growing Oleanders: Tips at a Glance
Evergreen flowering oleander shrubs thrive in warm Mediterranean climates (including USDA zones 8 to 11) and have slender, elongated foliage similar in appearance to an olive tree.

Oleander: A Field Guide
Oleander shrubs have much to recommend them: the flowering, evergreen bushes grow quickly to create tough, hardy privacy screens and windbreaks where you need them most in the garden.
As for drawbacks? Nerium oleander is the most commonly grown poisonous garden plant in USDA zones 8 to 11. Toxic to humans and other mammals, it can be fatal if ingested (within the past two decades, two toddler deaths were reported). With that in mind, site plants carefully if you have small children.
All oleanders belong to a single species, but there is a wide range of size, shape, and color available in cultivars: from dwarf oleanders such as ‘Petite Pink’, which can be shaped into low hedges to 20-foot high varieties that behave like small trees.
