Goat head flower and leaves Tribulus Terrestris is known by many other names such as: Caltrop, Puncture Vine, Tack Weed, Bull Head, Goat Head, Cat Head, and Mexican Sand Bur. As foreboding as these names sound, the reality is even more sinister. Caltrop plants like to stay very low to the ground, where they can escape the wrath of lawnmowers, weed-whackers, bush-cutters and other similar enemies. Keeping a low profile, their tentacles sprawl out quickly and quietly in a generally radial fashion from its central headquarters to form a far-reaching network of evil intentions. Each plant can produce several hundred to several thousand stealthy, strong, and sharp caltrop-like burs that have the potential to seriously injure people, animals, and even thin-walled pneumatic tires (like bicycle tires).Fortunately, they also produce small, yellow, bee-foraged flowers that serve as a subtle warning for the wise. You have been warned!HOW DID IT GET THERE? According to numerous reliable sources, Puncture Vine originated from southern Europe and northern Africa. Supposedly, it was (accidentally) imported into the United States along with livestock from the Mediterranean area. Bummer!
