Didn't even know you could buy florets on their own (get my veg from the market emoticon)
Frozen broccoli works well in broccoli and cheddar soup.
DD loved it from weaning. DS had it offered to him weekly for a year before he would agree to taste it (age 3) and then we went down the trees route with a whole story about how when autumn comes the leaves come off the trees which we had to repeat until he'd eaten the floret, then he started telling the story himself and he just eats the stuff (age 8).
DH and I like broccoli in quiches (with goats cheese or with salmon) but DCs don't really like quiche and Jamie Oliver's broccoli salad.
We all like it in soup and in my mixed veg dish which involves a lot of chopping but DCs ask for seconds of:
Melt butter and add diced carrot and broccoli stalk and slightly bigger chunks of waxy potatoes and a couple of garlic cloves chopped in half. Leave to cook with lid on until veg are soft, add seasoning, a little water and tiny broccoli florets and but lid of for about 5 mins or until they are cooked by the steam. If I have some I mix in a little bit of tinned sweet corn for the colour and heat through. It looks prettier and DCs love the stuff. Ensure when serving that all the chunks of garlic end up on my plate.
