Summer Broccoli

I planted some summer broccoli earlier this year but never got round to planting it out until recently hence the slower growth. It is now just over a foot tall. The question is, as with my Kol Rabhi, greyhound and prima cabbages and couliflower is it too late for them or will they go on through the winter. As I grew purple sprouting Broccoli last year it was ready in the spring to harvest. Will this be the same for my summer Broccoli ?
