Who could pass up a book titled Wicked Plants: The Weed That Killed Lincoln’s Mother and Other Botanical Atrocities? Certainly not I! Not only is the title attention-getting, but the book is a bilious acid green, the perfect color for poisonings!
I first heard about this book on the radio, and after about a month of waiting, I was able to borrow a copy from the library. After reading it, I had to get a copy for myself; no self-respecting naturalist’s arsenal of natural history reference books would be complete without it!
This tiny tome is chocked full of interesting information about some of nature’s most dangerous plants, many of which surprised me. For example, these days the news is smattered with dire warnings about giant hogweed and wild parsnip (members of the carrot family, yet capable of causing painful blisters and phototoxicity to those who brush up against them), but who knew that cashews could be problematic if not prepared correctly? Yes, cashews are related to poison ivy, poison sumac and poison oak. If eaten raw, or if they are contaminated with bits of the nut shells, the person consuming them can break out in a serious rash, which could be exacerbated if one is strongly allergic to urushiol, the irritating oil.
While many of the plants mentioned in this book by Amy Stewart come from lands far from the Adirondacks, there are a fair number that can be found within the Blue Line. Take, for example, elderberry. I remember collecting elderberry blossoms for my grandfather down along the railroad tracks that follow the Mohawk River. He used to make wine from the lacy white flowers. Well, it turns out that most of the plant’s parts (leaves, roots, stems, etc.) contain cyanide. This is especially true of the raw fruits. Cooked, the fruits are rendered more or less harmless, but when consumed raw they could send one to the hospital in a great deal of pain and discomfort.
How about cardinal flower? This brilliantly scarlet member of the genus Lobelia is found fairly commonly along waterways within the Park. As lovely as it is, the red color should be a warning. It contains poisons that are similar to nicotine, and if one were to eat it (although I don’t know why one would), one would likely suffer from tremors, nausea and vomiting, paralysis, and heart problems.
Not only does Ms. Stewart point out plants that are deadly, she includes those that are destructive (like purple loosestrife and kudzu), those that are offensive to the nose (purple trillium and skunk cabbage, among others), and those that actively cause problems (killer algae and gas plant).
I was so surprised at some of the nastiness that Mother Nature has in store for us that I was hesitant to burn the invasive honeysuckles we cut down last year. What if this aggressive non-native plant harbored some sort of chemical that was dangerous when set on fire? Nonetheless, burn it we did (the cut logs had started to sprout and had to be destroyed), and I can report that although I got a snoot full of smoke on several occasions, I have not suffered any ill effects.
Whether you are a plant aficionado, or a nature enthusiast in general, you will not want to pass up this delightful little book.
