If you look closely, you can seed the tiny nasturtium seed in the center of this flower. I never gave it a lot of thought before, but I assumed the seed formed after the bloom faded. If you are the ambitious sort, you can gather the seeds (after the petals fall, of course) and replant them next year.
If your nasturtiums are a hybrid, the seeds will not produce true to the parent, but you may get some interesting varieties this way. I intend to pick the seeds and save them for next year.
Until Next Time . . . Happy Gardening!
