Janet, I just did a search, and the leaves look identical to the plant I've got, so I'm confident that you found the right family!
I sure hope this thing blooms! Without seeing anything that looked like a bud, I wasn't sure it was going to have any flowers. I really thought it was something that the previous owner had planted, until I saw it growing elsewhere. There are so many plants here that I've never seem before, and most are just weeds. Any time I see something that is in the flower bed, and out in the field, I automatically think it is a horrible weed that needs to be removed! Hopefully this one will surprise me!
