Beginner Gardening: Help with broccoli, please...., 0 by Farmerdill

Broccoli is one of those plants where you actually eat the seedheads. So you actually want it to bolt (send up seedheads). The point is that that you must harvest the seedheads before the flowers open. Sometimes under stress, the plants will prematurely form small seedheads ( button) or if caught by heat or drought stress later in the season put up straggly uneven heads. If you have flowers, the broccoli has done its thing, you just missed the edible stage, which is the unopen flower buds.
