I've got a couple of mystery plants in my garden I'm hoping you can identify for me.
The first one I thought might be a sunflower at first.
But no, it's producing little yellow flowers:
Which in turn are becoming some kind of fruit(?):
There are only a couple of these plants, so I'm leaving them until I can figure out what they are.
(Edit: Thanks to commenter Molly, who pointed me to Name That Plant! at GardenWeb, and to Carol23 there, who made the ID, this I now know is Abutilon theophrasti, a.k.a. Velvetleaf, China Jute, Buttonweed, Butterprint or Indian Mallow. Definitely a weed. Darn it.)
Still looking for an ID on this one, though: In the vegetable garden is something that looks vaguely pepper-like in its leaves and habit.
But the flower is more nightshade-like:
It could be a vegetable of some kind, from seeds that have lain dormant until I started watering the long-neglected garden again. Or maybe it's just another weed.
(Edit: The consensus is that this is a nightshade, of the poisonous, weedy variety. Guess it doesn't matter which kind in particular. I've pulled it out. Thanks to everyone who weighed in!)
