I have compiled a list of succulent plants that are easy to care for and almost impossible to kill. When plants have insufficient light and grow leggy, that can't be undone. Sedums are easy-going plants that require little maintenance. They thrive outdoors in bright sunlight to full sun. This cactus tolerates drought and enjoys full sun. Kalanchoes are best suited for natural sunlight that is bright and not too intense. However, they do well in partial sunlight. If you have children or pets, it is important to be cautious.
