I've just put random carrots in and they look to be doing well - doubt that they'll make it to full size but I'll just behappy with a nice quick crop of baby carrots before the weather goes.
I did beetroot at this time last year and they did well.
Likewise the turnips that I put in last month are going well: baby turnips again.
I think that you might be a little late for sprouts and parsnips, but with the limitted life of parsnip seeds I guess you'll not lose too much by trying.
