It is handy to know what zone you live in when purchasing plants. Illinois is a big state and the plant hardiness zones range from 5a in the very northwest corner to 7a at the southernmost tip. Unless you live along the Kentucky border your winters would probably be too cold for your glads to successfully winter over in the garden.
Glads do produce seeds in those pods. Save the seeds and try planting them next spring. It will take several years of digging and replanting the corms before they produce a corm large enough to blossom.
