First of all, since your in chicago, you should give me some seeds you know? Second of all, the good ones are usually a brownish color sometimes with stripes. Also you have to check if they 'squish' when you press your finger on them. Finaly you have to see if they sink in water. If they pass all the tests then they probably will germinate if done correctly. Goodluck to you.

P.S. SEND ME SEEDS!!!
