Talk about foolproof: Annual begonia is about as easy as it gets. It does well in a variety of conditions, but to keep it its most luxuriant best, give it light shade; rich, well-drained soil; and ample water. It also loves plenty of fertilizer, so be generous.
Plant annual begonias in spring after all danger of frost has passed. No need to deadhead this flower unless you want to, it's "self-cleaning!"
