So I'm good with pulling the plant and being done with it. My question is - how do you get cabbage seeds? How long does it take? Do they bolt like lettuce and cauliflower?
Cabbage is biennial, (taking 2 seasons to produce seed), being part of the large family Brassicae spp. This big family, the Brassica's, consists of many species, including rutabaga/turnips, broccoli, cabbages of all kinds, kale, Brussels Sprouts and most of the mustards, to name but a few.
Most brassicas require a cold treatment (vernalization) in order to flower. After first year production, cabbage plants should be dug up and overwintered in a root cellar with the roots buried in sawdust or sand. This means it grows this year, over-winters and then seeds next spring.
