Inspired by the various brassicas questions, I was thinking of trying to grow some. Choosing something that I would eat, I'm thinking of either broccoli and/or cauliflower.
From what I have been able to read about growing them in a N.Texas climate, I can grow them as a fall crop (plant a few weeks ago and race against the first frost) or as a spring crop (plant after the last frost and race against the summer heat).
However, this recent question about wind tolerance implies that broccoli has some frost tolerance? Is this true? Could I plant seed in February (say) or even November and over-winter them outside, giving them a head-start when spring comes? Or would I be better off starting seed indoors in seed trays (in February?) and planting them out in mid-March after the last frost?
Is it possible to buy broccoli/cauliflower "starts" that could be planted in March? Pepper plants purchased in March always have a head start over seedlings during the spring / early summer months, so it seems like this might be a good idea for brassicas as well?
