Hi Karen, the
plant in the first picture looks like Velvet Leaf, Abutilon theophrasti. Are the leaves super soft to the touch? They will develop small, yellow
flowers under the leaves and then a very interesting
seed pod.
Some people consider them an invasive
weed, some say they are just wildflowers that are aggressive. I have one or two pop up occasionally and put them in a container because I think they are a beautiful
plant. They do like moisture so water frequently.
