Mountain Laurel
If you live in eastern North America, you’ve likely seen Mountain Laurel in your backyard. But stay far away from this poisonous plant. It’s commonly found in wet, high mountain meadows with a lot of rain. It’s not only an attractive plant, but it’s also deadly. Immediately after someone consumes the flower, they’ll experience burning lips and throat, followed by low blood pressure, drowsiness, weakness, convulsions, and paralysis followed by death. Previously, children have been poisoned and killed by simply sucking on the flowers of the plant. If you ever come across honey made from mountain laurel pollen, stay far away from it. It’s highly toxic (FS USDA).
