You can save broccoli seeds though the seed takes a long time to mature. Let the pods dry and go brown. This can take a couple of months.
Once brown, crack them open and you'll see dark brown dots. Those are the seeds. Store in a cool, dry place until planting time. You can tie a paper bag over the pods so that the day that the dry pods shatter, you don't lose he seeds. Also, keep in mind that broccoli will cross with all members of Brassica oleracea so you want some distance between the plants for pure seed!
