In her new book, “Wicked Plants: The Weed That Killed Lincoln’s Mother & Other Botanical Atrocities,” the Eureka, Calif.-based writer offers up more than 200 examples of botany’s bad boys and girls, along with anecdotes - and fun, if sometimes horrific, facts – that place the plants in the context of history, legend and science. Stewart recently answered a few questions about the plant kingdom’s “criminal element.” Q: Please explain your insatiable fascination with the dark side of the horticultural world.
A: I’m interested in these plants as characters, and the most interesting characters are somehow flawed. I like outcasts and miscreants. Plenty has been written about all the pretty plants we love. I thought it would be fun to explore the plants we hate.
