Annual flowers for full sun


Pansy and viola.
Annual flowers, those that die at the end of the growing season, provide us gardeners with an easy way to test colors and flower height in our landscape design. Annual flowers are less expensive than perennials, making annuals a good choice as accent or filler plants. In addition, annuals are good choices for flower pots. The following flowering annuals are suited for full sun.
