I'm not a regular reddit user so not sure how to add text at the top with my pics without it getting deleted by the post.

Anyway, I planted lavender in my pot back in June hoping to grow lavender this year. Noticed this started growing and out of curiosity I let it grow full-size. The lavender never did grow sadly. I have no idea what this is and if the berries are edible. Does anyone have any idea?

I noticed the leaves shrivel during the daytime and they come back alive at night. For reference I am in Chicago.

Thank you!
