I've got a few of these growing in a mulch pile behind my house. The started from nothing this spring and some grew as tall as 12' already with a 1.5-2" think stalk and a reasonably hearty root system.
It seems like some kind of weed.

Banana for scale...

They are seeds from the Velvetleaf aka Buttonweed plant (Abutilon theophrasti) which is an invasive species originally from China.

It looks to me like some type of thistle relative, which is indeed a weed. It might help people who know way more about plants than I ever will if you say what part of the world you're in.
Also, I applaud the use of the banana for scale.
