Nasturtium (Tropaeolum majus) is an annual flower. The Incas treated it as a salad green, only more colorful. The entire pepper-flavored plant is edible, including the seeds. In the garden, nasturtium develops quickly, producing flowers in tones of red and yellow. When those flowers dry, you have the option of collecting and storing its seeds. With minimal care, flower seeds remain viable for one year. With additional conditioning and proper storage, they will still germinate 10 years from now.
