Found growing in large pot of Gloriosas- pretty good sized plant

Kind of looks like Johnson grass (Sorghum halapense)
We need additional pics... grasses can be difficult to id.

It reminds me of Millet that is sometimes included in bird seed mixes. It may have been a "gift" from the birds.

Stripe down the center.

It does look like Johnson Grass to me too. However, something similar is coming up around my bird feeders. Do you have a bird feeder near that spot?

No bird feeder in the area, pot situated in rock strip that is host to a large evergreen and several large container plants next to concrete driveway. I'm tending to the sorghum though millet seems practically a first cousin.

I believe Stone nailed it ... check out these photo's of Sorghum halepense: http://floraitaliana.blogspot....

Thanks.

Will you be making syrup from it? Mmmmm...love that stuff.

No, that's the only one.
