Information about  Nerium oleander from other sources

[Wikipedia] Taxonomy: he taxonomic name Nerium oleander was first assigned by Linnaeus in 1753.[7] The genus name Nerium is the Latinized form of the Ancient Greek name for the plant nerion which is in turn derived from the Greek for water, neros, because of the natural habitat of the oleander along rivers and streams.
