At first glance, Paul Riddell sounds like a nice guy, but don’t tell that to the victims of his insect-devouring, killer plants. In an entertaining article for the Dallas Observer, Andrea Grimes profiles Riddell, a sci-fi writer-turned-horticulturist who found his true passion among carnivorous flora. Riddell loathes the perception of urban gardening as a tame pastime. He wants to make plants exciting at any cost, even if it means feeding a poor cockroach named Archy to Bub the pitcher plant in a viscera-bathed insect sacrifice. That gruesome scene formed the centerpiece of the first issue of his newsletter, the Hell’s Half-Acre Herald (unfortunately not available online, but you can read about it on Riddell’s blog).
