Note the Yellow Oleander blossom on this bush at the end of my driveway. This is the first time I have seen a blossom. It's beautiful, isn't it. Well take a step back.
The Oleander is one of the most poisonous plants with a extremely high toxicity from many dangerous compounds, many of which can be deadly to people, especially young children. The most significant of these toxins are oleandrin and neriine, which are cardiac glycosides which are present in all parts of the plant, but are most concentrated in the sap. Oleander is also known to hold its toxicity even after drying.
It is thought that a single handful or 10-20 leaves consumed by an adult can cause an adverse reaction, and a single leaf could be lethal to an infant or child!
According to the Toxic Exposure Surveillance System (TESS) in 2002 there were 847 known human poisonings in the United States related to Oleander (Watson 2003). These deaths occur disproportionally in Hawaii. Most animals can suffer a reaction or death from this plant.
Ingestion can cause both gastrointestinal and cardiac effects. The gastrointestinal effects can consist of nausea and vomiting, excess salivation, abdominal pain, diarrhea that may or may not contain blood.
Cardiac reactions consist of irregular heart rate, sometimes characterized by a racing heart at first that then slows to below normal further along in the reaction. The heart may also beat erratically with no sign of a specific rhythm. Extremities may become pale and cold due to poor or irregular circulation. For me, this would be similiar to my most infrequent visits to the dentist.
Reactions to poisonings from this plant can also affect the central nervous system. These symptoms can include drowsiness, tremors or shaking of the muscles, seizures, collapse, and even coma that can lead to death.
In Hawaii, many live off the land. It would surprise the tourist how many who live here are homeless. Eventhough the weather is friendly to the homeless, dangers remain.

A bumblebee should be in a world of joy within this blossom. Gecko took this one as well another twenty yards down the road.
