brocolli still edible?

Due to the weather constantly swinging from cold to warm this winter, my brocolli "bolted" & started growing little yellow flowers. I cut the heads that had flowers off & left the plant hoping it might grow more sprouts when the weather gets cold again. But as far as the heads I cut, if I remove the flowers can I still eat the brocolli? & if I dry out the flowers will there be seeds I can use next year?? I hate the idea of just throwing all the heads out but don't know if they are still edible. Thanks guys.

Did you post your question in more than one place?

Yes they are still edible. When I see mine start to bolt I harvest them ASAP and cook/eat them just the way they are.

gymgirl yes. always. I talk to ppl on one forum that might not always go on another but are very helpful.
