The easiest vegetable seeds to save for a 'novice' seed saver: beans, lettuce, peas, tomatoes, peppers, and okra. Legumes (bean & peas) are by far the easiest seeds to save, and also the easiest to germinate. There are numerous flowers which easily lend their seeds, such as marigold, zinnia, morning glory, cleome, nasturtium, poppy, snapdragon, and sunflower (Image courtesy: giantveggiegarden.com).
