Throw some cheese sauce on them and call it broccoli.

We have a seedling or 2 a year that do this- we call it the "Green Thing" & I use it in arrangements-- then people want to know where thay can buy it!! We generally don't get as much hard center as yours has but more of the frilly bracts-- almost a cluster of them.
There was a long complicated answer when I asked a botanist friend about it- something about the genes getting messed up & a cluster of the green bracts are all you're left with. This year we had one that had one petal & all the rest bracts-- looked like a rude finger if you know what I mean >:) There's even a fancy name for it but I can't remember what it is!
They look really cool in a weird arrangement with Wyn's Eeekk!!

I think I saw some "green thing" oddities at the Snohomish Co. show a couple years ago, Cory. Perhaps at the National Show earlier than that down in Seatac. They were not unattractive: just flowerless.

Cheese sauce! Perfect. I may save the tubers and consider the progeny a source of vitamin A, Granny. They had really great stems too LOL.

It was probably at the ADS show. I think Angus Hunter took some there that year. All the big-wigs were appalled & all the cool, funky people went-- "WOW-- what's THAT!!"
That was the same year we entered it on the ADS bench in Vancouver just for fun. We got the first & last DO-NOT Award-- the judges there had a sense of humor & hung a do-nut on it. (Someone stole our do-nut the next morning!)
