That number is no typo. Humans started cultivating and domesticating cabbages from the wild somewhere around 1000 B.C. And they have been hooked ever since. I haven't reached my first millenium of experience growing them yet, and I have only grown them in containers; but I can certainly say they are worth the modest effort I have to put forth for them. They are a cool weather crop that loves the spring and fall of NWI. And cabbages are like goldfish. They grow to the size of the space available to them. I just harvested a cabbage grown in one the smallest containers I've ever used, about one gallon. The head was the size of a large fist, but when sliced it provided more than enough for a nice pot of cabbage and sausage soup. The old proveb is certainly true, "Big things come in small packages." And often tasty things do as well.
