No 2 is a potato.

The top one is possibly Abutilon theophrasti - not a plant I have ever seen myself.

I would have guessed that the first ones were sunflowers...

The first one is a velvetleaf.

Here is a link that might be useful: velvetleaf

Agree #2 is a potato.

Yup, velvetleaf and potato.....with some leaf miners nibbling through the velvetleaf foliage

Thank you my gardenweb pals! I'll pull the velvet leaf and let the potatoes rip!

Just for clarification if you didn't follow the link, Velvet leaf is Abutilon theophrasti.

Velvet leaf used to be called butterprint here. The seed pods make a distinctive radial pattern that was imprinted on butter.
