Collecting seeds from your herb plants is a great way to ensure you have a plentiful and free supply on hand for years to come. Apart from these benefits you will know the quality of your own plants and that they're bound to be disease free.
It's easy to collect the seeds; all you need to do is wait until they're fully matured and harvest them first thing in the morning before the sun is on them but when the dew has dried. Hold a well-opened packet or envelope under the seeds and using scissors or secateurs, snip the stalk so it falls in. After you have the seeds in the envelope or packet you can remove them from the stalk without losing any. Although some plants can take a while to produce seeds after flowering just as the above flat leaf parsley has, it's well worth the wait.
