Sunlight is a crucial component of every plant's daily life, but there are many flowers that actually require at least six hours of sunlight each day in order to thrive. Typically, sun-loving flowers are able to tolerate very hot temperatures, as well as drier soil conditions. For several months in the spring and summer, blooming full-sun flowers add splashes of color throughout gardens and yards.
Yarrow (Yarrow sp.) is a popular plant both for it easy growing habits and minimal care requirements. Despite its simple maintenance, yarrow does require direct sunlight during the day,as well as placement in a hot location. If this sun-loving plant receives too much shade, it will begin to wilt. Drier soil is preferred, and excessive moisture can actually cause the plant to die in the winter, according to the website Gardening-tips-perennials.com. Yarrow has many different cultivars, all of which begin to bloom in the early spring and continue to produce flowers into the summer. Flower colors include white, pink, yellow and red. Yarrow grows quickly and can easily become invasive in very sunny areas if not properly maintained. Yarrow is hardy in USDA planting zones 3 to 8.
Whorled coreopsis (Coreopsis verticillata) is a hardy flower that tolerates drought, high temperatures and poor soil conditions. Whorled coeropsis blooms prolifically throughout the summer, producing bright yellow daisy-like blossoms. Blooming continues until the first frost. The cut flower's longevity makes it a popular choice for fresh flowers, according to the Floridata website. Whorled coeropsis requires full sunlight during the day and prefers sandy, well-drained soil. Hardy in USDA planting zones 5 to 10, these nectar-filled flowers attract an abundance of bees and butterflies.
Throughout June and July, the shasta daisy (Leucanthemum superbum) blooms large white flowers with bright yellow centers. These cheerful plants grow up to 3 feet in height, according to the Planet Natural website. Shasta daisies thrive easily and require very little care, making them ideal plants for beginning gardeners. Although the shasta daisy is hardy and can tolerate partial shade if required, this plant prefers full sunlight, as well as well-watered soil that drains quickly. Shastas grow particularly well when planted together in small bunches. Shastas are able to live for up to 10 days once cut, making them a common selection for fresh flowers. The shasta daisy is hardy in USDA planting zones 4 to 10.
Peony (Paeonia sp.) plants produce stunning, often fragrant, flowers in a wide array of colors, including pink, yellow, white and red. Peony begins to bloom in the late spring and continues to produce flowers into the summer. Peonies flourish in full sun conditions with at least six hours of sunshine and prefer well-drained soil, according to the University of Rhode Island website. Peonies can grow up to 4 feet in height, and this, coupled with their large flowers, often requires that the plant be supported. Hardy to USDA planting zones 2 to 8, peonies are long-lived perennials that, if cared for properly, have been known to live for over 20 years.
