Annual flowers are types of plants that only grow for a single season. They can grow from spring well into the fall, and they die off when the freezing weather comes along. They won’t grow back in the spring unless you plant them again. This is a direct difference from perennial flowers where a small part dies back when it freezes, but the roots live and the plant re-grows again in the spring. Many people like annual flowers because they’re a fantastic way to switch up the look of your garden from year to year, and they make great backyard and pond design pieces.
