You'll be amazed at the endless variety of colors that a single ear of glass gem corn can produce. Corn stalks grow to 8 feet tall and produce several ears of corn ranging from 5 to 8 inches long. The ears and stalks are great for ornamental use, and the kernels may be used to make popcorn (I recommend using an air popper). The dried kernels can be ground into cornmeal. Each packet contains 60 seeds.
