Does it flower?

Not sure. Its got those Things. growing out of the top. Looks like it could be turning pink or purple. Could be a flower before blooming or seed . Not sure yet.

I think it's some type of green ti plant.

Sorgum

Close to sorghum - but not sorghum. Johnson grass... definitely a nasty weed. http://www.idahoweedawareness.net/vfg/weedlist/johnsongrass/johnsongrass.html

It is NOT Johnson Grass. Johnson Grass is much taller and thinner. It appears to be some other type of Sorghum. I suspect some bird deposited it after consuming commercial birdseed.

Millet it is a seed in birdseed and can be ground to make flour

It is definitely a type of sorghum. It looks like corn as it grows, then gets the seeds at the top. I agree that a bird must have carried the seeds there.

I actually like to use it in fall arrangements when it dries. I spray it with hairspray to keep the seeds in place. Just catch it before it drops seeds, or you’ll have a bumper crop next year!

It's grain sorghum also known as milo. It's used as feed for cattle and hogs.
