Saving Seed From Nasturtiums For Planting
Nasturtiums are one of those plants that are easy to grow and produce a great deal of seed once established in your garden. After flowering has finished the nasturtium leaves a green pea sized seed that you can harvest the seed by picking it off the flower vine. Sometimes seeds fall to the ground and dry, you may find brown seeds below the nasturtium vine. Generally I dry mine out in a greenhouse or warm location, sitting the seeds in a big wide container. When the seeds turn brown and wrinkle they are ready to plant. Once the nasturstiums are established in an area they will self-seed readily, keeping your garden filled with colorful flowers.
