Ideation 8,217 Posted May 3, 2011 Report Share Posted May 3, 2011 300 million years old. They spread like f**k, they are also really poisonous to livestock. Only way to get rid of them is to remove the top 2 meters of soil, or posion it to f**k. It's taking over the world 10 cm rhizome can turn into up to 64 meters in one year. When the top thing sheds it chucks out 100,000 spores. Quote Link to post Share on other sites
