[[Impatiens]] are likely the number one bedding plant in the United States. These easy to grow plants are usually perennials grown as annuals, though in warm climates they live for years. Part of their popularity is due to the fact that they're easy to grow from seed, bloom quickly, and don't stop until frost kills them. Ripe seed capsules explode upon the slightest touch, shooting little seeds around, earning them the nicknames Snapweed and Touch-me-not.
