What Are These Plants?

Question

I found one plant growing in a pot with my other plants. The other one with the pretty yellow flowers is probably a weed, but I’d like to know. Could you identify them for me, please?

The plant in the container looks like pokeweed, though it usually has some pink or purple on the stems. You will know for sure if it flowers and produces a raceme of berries, similar to small grapes. If so, I don't advise keeping it. The leaves and berries are poisonous, except to birds who will eat them and drop seed everywhere and before you know it, pokeweed is growing all over the yard and is hard to pull up.

The yellow flowered plant is common wireweed (Sida acuta), and is useful as a native plant for wildlife. If left uncut, it can grow into a 4-foot shrub.
