This plant appeared in our garden this year. We did add some dirt this year, so maybe that is how it got there. There are several of them with the largest 10' tall. The stalk looks like bamboo, and the leaves are very large and growing in clumps of 8 I think. One has a red stalk and the others are green. It is growing in our pumpkin patch.
Can you help identify this please? Is it invasive or dangerous? What should we do with it?
Thanks for your help!
