The solid whites, reds and a variety of pinks are the most common.

Larvae of the common crow butterfly (Euploea core) also feed on oleanders, and they retain or modify toxins, making them unpalatable to potential predators such as birds, but not to other invertebrates such as spiders and wasps.

The flowers require insect visits to set seed, and seem to be pollinated through a deception mechanism.

Among these compounds are oleandrin and oleandrigenin, known as cardiac glycosides, which are known to have a narrow therapeutic index and can be toxic when ingested.

Toxicity studies of animals administered oleander extract concluded that rodents and birds were observed to be relatively insensitive to oleander cardiac glycosides.

It is most commonly grown in its natural shrub form, but can be trained into a small tree with a single trunk. The toxicity of Oleander renders it deer-resistant and its large size makes for a good windbreak – as such it is frequently planted as a hedge along property lines and in agricultural settings.

The plant is tolerant of poor soils, intense heat, salt spray, and sustained drought – although it will flower and grow more vigorously with regular water.

Some invertebrates are known to be unaffected by oleander toxins, and feed on the plants.
