Author Karen Sackett informs readers of all ages of the wily ways of weeds, including the creepy trickster Dalmatian toadflax, which looks like a garden snapdragon but spreads long distances underground, and the hitchhiking outlaw houndstongue, whose Velcro-like burrs cling to fur and clothes. You'll learn how "special agents" in weed control are reining in these outlaws, and you'll find out what you can do to help.
