Where are you located? What kind of season do you have? Could you post a photo of the plants so we have an idea of what you are working with.
Down here on the gulf coast I transplanted broccoli early October and had some nice heads over the winter. It produced several small sucker heads too but it finally gave out. The previous year I transplanted in January, total failure. When I was in Arkansas I'd transplant broccoli late February- early March. Sometimes I'd get nice heads and suckers, sometimes it was a total failure.
The way broccoli goes to seed is that it forms the florets that we eat. If you leave them on the plant yo see yellow flowers from the, you waited too long. If they have not started that you may be OK. If you've seen any yellow flowers, I'd pull them.
