When you said "normal edible" sunflower seeds, do you mean you planted seeds you bought for snacking? If so, there's no way to know what to expect.

If you did plant packaged seeds for home growing, it sounds like the pot is too small for the large varieties. They need a 3 to 5 gallon container. The roots of a sunflower grow wide and deep. They need fertile soil and full sun - 6 to 8 hours a day. Here is more info:
