Just planted two castor bean plants, from which you get both castor oil and ricin, in an open area where I can keep an eye on ‘em. This’ll be nightmare fuel for days.
Kinda surprised that the nursery I got them from, which is a pretty reputable place that’s gotten big in the area marketing organic gardening classes and selling chickens and that sort of wholesome thing…not only didn’t keep them behind glass in a locked cabinet like aerosol spray paint in the art store, but didn’t even mention anywhere on the label or the sign that these little guys were “THE WORLD’S MOST POISONOUS PLANT”.
Of course, that last is A. from USA Today and B. from 2006 and the angle they were pushing was terrorists are coming for your landscape plants. On a more reasonable note, the seeds are the most poisonous part of the plant, and you can avoid having to worry about those by just deadheading the spent flowers rather than allowing them to develop into pods. (Still pretty horrifying to read the castor bean section on, I think, Dave’s Garden, with at least one person asking what they should do if they wanted to make lotion from the deadly seeds, should they just, you know, mash up these seeds in a blender? WTF NO DON’T DO THAT.)
