Thumbing through a book of toxic and hallucinogenic plants, I finally manged to i.d. the neighbor’s shrub that looms over the staircase to our front door. The popular name given for this plant in the book was “suicide tree”, so named for its use in Sri Lanka, though I’ve found other plants with this same moniker. The scientific name is Thevetia peruviana, and it’s also known as “lucky nut” (can we change that to unlucky nut please?), Be Still Tree (presumably because you’ll be still if you eat any of it), and yellow oleander (it’s a relative of Southern California’s favorite freeway landscaping flower). I was able to dig up a research study on what the authors described as an “epidemic” of yellow oleander poisoning in Sri Lanka,
“Accidental poisonings occur throughout the tropics, particularly in children. Adults have died after consuming oleander leaves in herbal teas. However, deliberate ingestion of yellow oleander seeds has recently become a popular method of self harm in northern Sri Lanka. There are thousands of cases each year, with a case fatality rate of at least 10%. Around 40% require specialised management and are transferred from secondary hospitals across the north to the Institute of Cardiology in Colombo”
Native to central and south America Thevetia peruviana made its way to Sri Lanka only recently, with the suicides starting up within the last 25 years, according to an article in Bio-Medicine. Apparently news accounts of suicides have fueled its use. The Bio-Medicine article describes a typical incident, “I remember one girl said her mother wanted her to get up and do the shopping. She said no, her mother scolded her and she took a yellow oleander seed.”
A semi-popular landscaping plant, it grows without any water or care here in Los Angeles, though a hard frost would kill it. The elderly neighbor who used to live next door told me that she brought it with her from Mexico. I’ve seen it growing in vacant lots and by the freeway, so it seems to be able to spread on its own. So why put it on the least favorite plant list? It’s neither beautiful nor useful (unless you want to kill someone or hate shopping) nor does it seem to provide habitat or forage for beneficial wildlife. Why plant something that can accidentally poison a toddler?
