Annuals live only until the first frost and then die. Their life cycle (in Michigan) is spring through fall. Since they have color the entire season, a good garden will usually have some annuals mixed in to brighten it up when no perennials are in bloom. To get you started, here is a list of some easy-care annuals for Detroit, Michigan.
