Deadly serious plants

Posted on Wednesday, August 12, 2009 in random science

Whenever I’m pulling deadly nightshade out of the garden I get terribly curious about how the fruit of this plant must taste. I’m thankful that I never had this urge while I was a child. I also get to thinking about how I could try a witch’s flying potion with ingredients from my garden: nightshade, monkshood (aconite) and poppy being right at hand.

So I turned my curiosity towards other poisonous plants. And there are many.

Daffodils

For example, my beloved daffodils are poisonous. Or, at least, the bulbs are. I’ve read that Roman soldiers carried the bulbs to be used as a sort of cyanide pill (0r in this case an alkaloid  pill) to commit suicide rather than die of painful sword or spear injuries. Botantical.com informs us that “an extract of the bulbs, when applied to open wounds, has produced staggering, numbness of the whole nervous system and paralysis of the heart.” No recipe for the extract is provided, thankfully.

Not onions

At least the squirrels are smart enough not to eat daffodil bulbs. (Although they’ll still dig them up for the fun of it.)

Apples

What could be safer than an apple? I recall the Alar and apple scare back in the 1980s, but we’ve all been eating an apple a day since then, right? I think I’m still safe in doing so. But not those lazy or thrifty people who eat the entire apple. If you eat enough of the seeds, apples can kill you. The pips hide cyanide within. Luckily we can detoxify small quantities in our own bodies, so you’d have to swallow a lot of the seeds before succumbing to the poison. Still, it’s a little disconcerting to see the ubiquitous fruit listed in Poisonous Plants of North Carolina.

La ngong and yellow oleander

If you don’t want to commit suicide with some common plant like lily-of-the-valley or rhubarb, you could go the route of folks in Vietnam or Sre Lanka.  I found a report on la ngong (Gelsemium elegans) being used for suicides in Vietnam in 2007. It’s a very lovely vine with yellow flowers. It must be hard to pass by. Six people died after drinking wine in which the roots of the plant had been soaked.

Sri Lankans prefer to use the  yellow orleander. It sounds rather romantic and dramatic. And for a while, it was quite the thing to do. “Yellow Oleander Plants Fuels Suicide Rates In Sri Lanka” reads a headline from 2006. You can also find all sorts of medical reports on the problem.

Mallow and puffins

Plants don’t just cause us harm; they go after cute fluffy animals, too. And in cruel and weedy ways. Consider the mallow which most gardeners curse themselves for ever planting. It’s evil enough. But another variety of the mallow, the tree mallow, is after the puffin. It covers the ground so thickly that the puffins can’t make nests.

‘The puffin only makes things worse for itself,’ added van der Wal. ‘It breaks up the ground, providing a perfect place for tree mallow seeds to take root. The birds provide homes for tree mallow which then prevents them breeding. Nature can be cruel.’

If you’re curious about other poisonous plants, there’s a quirky little site written by the Poison Garden Warden. After checking it out, go watch the video at the Alnwick Gardens site.  I HAVE to go visit the garden. They grow cannabis in a cage!
