What's my broccoli doing

Its been growing strong since Spring with no problems other than a few holes in the leaves.
Having never grown them before, I dont know what to look for or when to expect some "florets" to appear.
Any advice please :?:

Which variety is it please?  Early Purple Sprouting for example would normally pick in Feb / Mar

HI  WG, The seed packet was just called "Broccoli White" - I think.

But I see from your comment that I have to wait all through the winter before I can expect anything .... and then I may get some florets :?:
