Googling "wonderflowers" I get a commercial page with a photo of Mirabilis jalapa.

I just bought some at the Chicago Flower show and in looking around I'm finding that it is the bulb Four O'Clocks which is not winter hardy but supposedly reseeds profusely. I think we probably paid too much for bulbs that we could have simply bought some seeds if we wanted Four O'clocks. I'll probably try them just to see what they look like since I've made the investment!!

I totally agree with you melrose. I paid about $15 for 5 bulbs of the four o clock plant. Really feel kind of bad seeing all my local nurseries are selling the seeds for under $2.
