Unknown Outdoor Plant

I have attached pictures of a plant which came from old assorted seed package. Does anyone know waht it is? It appears to thrive without much water.

Thanks,

One of the selections of Malva sylvestris, looks like.

 

Thanks Abgardeneer,

I went to Google after your reply and found pictures which show this to be a species of Malva.

 

One other thing to watch out for - we had one of those several years ago (because it was such a nice looking plant) and now we have seedlings coming up everywhere. At least they are easy to pull out.

 

I think these are commonly called Mallows.
