This most classic of the corpse flowers is also one of the easiest species to grow, even tolerating moderate freezes in-ground. The plants can produce leaves between 3-6 feet tall and of similar width, bearing dark green petioles speckled in lime, and once tubers are mature (anywhere between 1-20 pounds and a foot plus in diameter) they can send up flower stalks between 2-6 feet tall, topped by a ruffled maroon spathe surrounding a similarly colored spadix and cream flowers near its base. And of course, famously "corpse flower" due to the powerfully rotten odor it gives off for the first few days after opening.
