> Japanese knotweed tubes (don’t grow it yourself, it’s highly invasive)

Last year I was lamenting to a neighbor that bamboo doesn't survive the harsh winters where we live. He disputed that.

"There's some growing down the road, next to the ditch," he said. "It comes back every year. It's everywhere."

I was wondering what the heck he was talking about and then I realized it was Japanese knotweed. The segmented branches do look like thin bamboo, and he claimed that at one time it was sold at the local garden center as "bamboo."
