Shameplant. Humble plant. Sensitive plant. There are plenty of nicknames for mimosa pudica, yet none adequately prepare you for the behavior that makes it such a creepy curiosity. Click here to see it in action: Upon being touched or shaken, the leaves of the plant immediately shrivel, as if the plant were dead and decaying. Wait a couple minutes, though, and the leaves return to normal, as if nothing ever happened. For success growing the tropical weed indoors, plant in loosely packed, well-draining soil, ideally in a spot that gets plenty of light and warmth year-round. If your local nursery doesn't carry it, fear not—seeds are readily available online. Available at Amazon; $3.65 for 100 seeds.
