Annual flowers that thrive in the sun include petunias, zinnias, marigolds, hibiscus, floss flower, moss rose and sunflowers. There are also some hybrid versions of impatiens and caladium that are tolerant to the sun.
Petunias are popular plants for sunny areas. There are many different varieties available with different colors, patterns, blossom sizes and shapes. Although they prefer full sun, they can tolerate partial shade.
Zinnias are available in a number of different colors, and many varieties have attractive leaves. Some varieties are designed to be drought resistant, whereas others require infrequent deadheading. Zinnias need full sun to thrive.
Marigolds and sunflowers are other popular choices for sunny areas of the garden. Like other sun-loving annuals, these require at least six hours of sunlight per day to thrive, notes HGTVGardens.com.
The hibiscus is a tropical plant, so it makes sense that it prefers full sun. Other tropical annual flowers to plant in sunny areas include the canna and mandevilla.
The moss rose has small leaves and large flowers. It is very tolerant to dry conditions and does well in rock gardens, containers and borders.
Floss flowers have puffy looking blossoms that come in purple, lavender, pink, white and blue. They tend to prefer cooler weather, so they require some shade in very hot climates.
Although impatiens and caladium usually prefer shade, there are a few hybrid varieties that can thrive in the sun.
