Earlier this year we spent time preparing the planting bed along the fence in the backyard. We’ve planted zinnias, basil, morning glory, and transplanted a few other plants to the bed. This little specimen, however, was not planted by us, but I’ve let it grow from a little seedling into this big leafy bush. We’re not quite sure what it is yet. I’ve tried googling images on the web and think it’s a green pepper. It has some tiny white blooms on it, and I’ll wait to see what they turn into. Several years ago I did have green peppers planted in this bed, so it very well could be a volunteer.
When and if I get confirmation of what this mystery plant is, I’ll post an update.

Update as of 4/30. Survey says this is not a pepper. Sadly, it’s a weed — called Common Nightshade, whose foliage and berries are poisonous. The little white flowers turned into small green balls, which later turn black and spread like, well, like a weed. I’ve just dug this guy up. Adios Nightshade.
