Summer broccoli flowering

This year  i thought i would try some summer PSB. I only picked my first harvest about a week or so ago and it is already flowering is this normal?

Well it is summer, so no big surprise, its totally different to the over-wintering type :happy:

My suspicion is that many veggies will bolt or go to seed every year, the trick is to catch them before they do so.  They are annuals so their purpose is to produce seed for the following year - if you keep removing the veggies, they don't set seed and so continue to produce new veggies in the hope that you'll fail to pick them and thus they can achieve their purpose.

I don't know enough about the different types of broccoli to say whether summer ones are better or harder than other types.

The ones I'm doing this year are described as Calabrese Green Sprouting. I suspect I'm going to have to pick them pretty soon to stop them going to seed, because one or two are opening out already, but between seven plants the central sprouts don't amount to enough to feed two people for one meal
