  • Oleander   Oleander (Nerium oleander)   is a perennial, evergreen shrub, native to the Mediterranean region, and now widely distributed in most tropical and sub-tropical areas of the world.
  • Oleander is used as an ornamental plant in landscaping and as potting plants.
  • Leaves are simple, oblong-lanceolate, dark gray-green, leathery, with a prominent midrib and veins, and usually arranged in whorls of three.
  • White, pink or red showy flowers grow in clusters in spring and early summer.
  • All parts of the plant are toxic, including the dried leaves.
  • Humans, livestock, dogs, cats, birds and horses are susceptible to poisoning from oleander.
  • Human toxicosis has resulted from inhaling smoke from burning oleander.

  • Yellow oleander, found in Australia and Florida, is equally toxic.
