About this weed

Oleanders are large perennial shrubs or trees with red, pink or white flowers in summer. It is so widely cultivated that no precise region of origin has been identified, though southwest Asia has been suggested. This garden escapee has now become a problem mainly through the dumping of garden rubbish in bushland.  Oleander is one of the most poisonous commonly grown garden plants.

Description

Oleanders are a small spreading tree or shrub but can under some circumstances grow to about 5 metres high. The dark-green leaves are thick and leathery and narrowly lanceolate. Their erect stems splay outwards as they mature. It is a vigorous grower in warm subtropical regions although it can tolerate cooler climates. In summer Oleanders produce masses of red, pink and cream flowers. Oleander has historically been considered a poisonous plant because some of its compounds may exhibit toxicity, especially to animals, when consumed in large amounts.
