Author/Gardener Amy Stewart and reader Coleen Marlo have followed up Wicked Plants with a new audiobook detailing the sinister elements that could be lurking in floral bouquets, backyard gardens, or even that plate of vegetables on the dinner table. Wicked Plants: The Weed That Killed Lincoln's Mother and Other Botanical Atrocities continues in the vein of Wicked Bugs, giving a brief history of known botanical problems: poison ivy, hemlock, oleander, etc., but also adding tidbits about obscure plants to be assiduously avoided. While Coleen Marlo's playful tone makes the most of Stewart's creative descriptions, both the text and the reader continually emphasize the need for safety and easy access to the phone number for Poison Control when reaction to a plant is ever in question.

Marlo clearly enjoys herself as she reads through "Death by Lawn", "Weeds of Mass Destruction", and "Vegetable Wickedness". It is the little things that are the most interesting, though, such as Marlo's presentation of "ordeal beans", which, for a while in Nigeria became a Monty Python-esque method of determining innocence or guilt through the ingesting the toxic calabar bean. Or how simply passing by a henbane plant could cause folks to swoon, which is why ancient Romans attempted to use the plant as an anesthesia.

Stewart's research encompasses plants that strangle, sicken, sting, cause hives, and in general irritate through their seeds, leaves, fragrance, and oils. Marlo's delivery brings forth the irony and/or humor inherent in plants with names from "vomitwort" and "corpse flower". There are fascinating facts as Stewart details and Marlo presents the sometimes fine line between plant as healer - castor oil from castor beans - to plant as murderer - the horrific poison, ricin, is an extract from that same castor bean plant. There is malevolence to be found in the book from unstoppable water hyacinth vines, fast-growing bushes of purple loosestrife, and the pestilence of killer algae in our oceans. Wicked Plants tells of a world pretty much taken over by insidious plant life, perhaps increasing its sinister control while a human population is distracted by smartphones, computer screens, and iPads. Fortunately for the audiobook aficionados, listeners can remain alert to the encroaching kudzu while enjoying Amy Stewart's highly entertaining writing and Coleen Marlo's enthusiastic descriptions in Wicked Plants. Oh, and remember to avoid exploding plants! — Carole Chouinard
