It still looks pretty artichoke-y to me. Even though they look large and few in number, they still look like they are "trying" to grow in layers.

Different combinations of weather and photoperiod in a particular season are bound to have an effect on the size and number of cloves.

I think it may be an Asiatic turban type. They have those big cloves in the middle. I would expect them to be small in your climate because they finish early. If you let one bloom next year and develop bulblets, you will be able to narrow it down further. Some Asiatics have big bulblets and others have tiny ones.
