My broccoli plant has bolted and the flowers have disappeared. What do the broccoli seeds look like? I have one inch spike on the plant. Are those the young seeds? How long do I let them grow? Do I dry them out?

The head of the broccoli are immature flowers. You need to let the broccoli go to flower and allow it to get pollinated. It will lose its flowers and in their place will be little seed pods. They will mature over some time and several seeds will be inside a pod, over an inch long and a bit larger around than the seed. Harvest them when they are dried and tan colored. Break the pods open to get the seeds. This article will help with broccoli seeds: https://www.gardeningknowhow.com/edible/vegetables/broccoli/saving-broccoli-seeds.htm
