These plants randomly sprouted out in a little area outside of my garden fence. They spread like wildfire and have gone under?(it seems) the fence and are multiplying in my garden. They grow really fast, and are pretty tall, about 30-40cm. I tried digging one up and i got about 15-20cm of root b4 the root just snapped, Haven't been able to find the end of it. Searched many websites, but haven't been able to locate the name, and or how to get rid of it. they seem to have a very long root network and it's taken up a good 5th of my garden, approx a 3x7m area taken up, and it's still spreading and growing. if anyone could help identify, it would be much appreciated
