Many people don’t know that the oleander is the most poisonous flowering plant in the world. It has been used as a natural remedy since ancient times, but can also be a weapon. The yellow oleander is the national flower of Nicaragua, and while it is a beautiful and majestic plant, it can also be deadly.
Despite the habitat destruction and illegal harvesting, Oleander still flourishes in the wilds. It is planted as an ornamental plant in gardens and public parks and also grows in roadsides and wasteland. The most common way of propagating Oleander is by stem-cuttings or layering. Oleander is suited to tropical, subtropical, temperate and arid climate types.
