Answer: Cleome should grow well for you in Illinois. This plant is an annual, meaning it must be started anew from seeds each year. The seed pods are indeed on the ends of the wispy projections along the stalks. The plants should self-sow in place if allowed to set seed and then it scatters naturally in the vicinity -- they tend to germinate a bit late in the season when the soil has warmed so don't be too impatient. With luck they will come up so thickly that you need to thin them in the spring. You can also transplant small seedlings then. Finally, you could also save some of the seeds and plant them yourself next spring if you want them in another place. Enjoy!
