I have been trying to eradicate this one. To start with I thought it was kind of interesting, since the leaves get two feet across, but it gets four feet high and shades everything around it, and when I realized it was spreading from runners, I decided it was definitely a weed. I would like to know its name however. Mixed up with it is a purple leaved shrub that is sprouting from a stump. I thought maybe a smoke tree but I'm not sure. And the last one is also sprouting from a stump. And thanks for the answers to my first post. I will be getting rid of both of those.
