What Flowers Like Partial to Full Sun?

USDA Zone 2

• Despite colder climates such as those in USDA plant hardiness zone 2, there are flowering options for sunny locations. Trees such as the American linden, white willow and chokecherry produce conspicuous flowers. Perennial flower candidates are few for zone 2, but species such as creeping phlox, thimbleweed and the Song Sparrow hybrid of daylily take hold in this zone. Deciduous shrubs with fine flowering effect include common ninebark, a bush growing to 10 feet and putting out white June flowers. Siberian squill is a bulbous flower that features deep blue blooms.

USDA Zone 4

• The winters of USDA zone 4 are less severe than zones 2 and 3, but still test a flowering plant's hardiness. Still, more species for full sun are available, such as bulbous plants like nodding onion, prairie onion, crocus and glory of the snow. Trees with flowers for this region include catalpa, serviceberry and Juneberry. Catalpa in particular is an interesting specimen, with huge leaves, trumpet-like flowers and resulting hanging beanpods. Perennial choices increase in zone 4, with the daylily and coneflower cultivars in particular being abundant. Flowering vines are viable in zone 4; the clematis cultivars are especially numerous, including Little Nell and Golden Cross.

USDA Zone 7

• The sun-drenched spots in zone 7 are possible planting sites for broadleaf evergreens with flowers, such as Chinese fringe-flower and tree heath. Windflowers, chives and a plethora of lily species develop from bulbs in this zone. The perennials for sun in zone 7 list giant hyssop, coneflower, wild strawberry, iris, cranesbill and garden phlox among their ranks. Small 6- to 8-foot vines such as wild passion flower and much longer ones, like the potentially 60-foot crimson glory vine, flower profusely in the sunny climes of this zone.

USDA Zone 10

• The Mexican petunia, oleander and Shooting Star cultivar of gardenia are examples of broadleaf evergreens able to grow in zone 10's sunshine. Spider lily, crinum and pineapple lily do likewise as bulbous plants. Dwarf pomegranate and beautyberry are two types of deciduous shrubs handling the heat and humidity of a zone 10 summer and still turning out attractive flowers and fruits. Various water lilies, pennywort and cupflower are perennials for these conditions. Trees noted for their flowers in this zone include two kinds of magnolias, the sweetbay type and the swamp magnolia. Mandevilla and glory bower shine as flowering vines in full or partial sun in zone 10.
