Types of Outside Flowers in Dallas

Dallas, Texas, experiences a humid subtropical climate with mild winters and hot, dry summers. Dallas lies within the United States Department of Agriculture (USDA) Hardiness Zone 8a. Dallas gardeners should choose outdoor flowering plants according to plant hardiness, intended use, bloom time and general culture. Many flowering plant varieties perform well in Dallas gardens.

Purple Clematis

The purple clematis (Clematis pitcheri), sometimes referred to as the leatherflower or the bluebill, belongs to the buttercup family (Ranunculaceae). This climbing vine reaches up to 10 feet in length. Purple clematis plants bear heavily veined, light green leaves and nodding flowers that appear from May through September. The urn-shaped petals feature red or purple outsides and green, red or deep purple insides. This drought- and heat-tolerant plant fares well in Dallas gardens, but typically dies to the ground come autumn. This perennial prefers moist soils in partly shady to fully sunny locations. Gardeners generally train the purple clematis to climb trellises and fences.

Texas Frogfruit

The Texas frogfruit (Phyla nodiflora), also called the turkey tangle frogfruit, belongs to the verbena family (Verbenaceae) and reaches between 3 and 6 inches tall. This perennial features green leaves that take on purple or red tints during cold weather. The white flowers bloom from May through October. The Texas frogfruit tolerates various soil and lighting conditions. This drought- and flood-tolerant plant sometimes spreads aggressively. Dallas gardeners use Texas frogfruits as outdoor container plants, groundcovers and butterfly garden flowers.

Apache Plume

Apache plumes (Fallugia paradoxa), also known as ponils, reach up to 6 feet tall. This rose family member (Rosaceae) features an upright form, gray-white branches and dark green leaves. White flowers bloom from May through December, followed by pink fruit plumes. This perennial shrub prefers dryer, sandy or gravelly soils in partly shady locations. Dallas gardeners often plant the Apache plume in rock gardens and woodland areas. This plant also works well for erosion control.

Sacred Thorn Apple

The sacred thorn apple (Datura wrightii), also called the datura and the jimsonweed, is a potato family member (Solanaceae) that thrives in Texas floodplains. This herbaceous annual features white, trumpet-shaped flowers that bloom from May through November. These flowers open near sundown and wilt by the next morning. This plant also bears coarse, foul-smelling foliage. The sacred thorn apple prefers dry, sandy or loamy soils in various lighting conditions. Mature plants reach up to 6 feet in height and contain toxic properties. Dallas gardeners generally use the sacred thorn apple in bog gardens, pond margins and perennial flowerbeds.

Wild Foxglove

Wild foxglove (Penstemon cobaea), also called prairie penstemon and false foxglove, blooms in April and May. This figwort family member (Scrophulariaceae) features tubular flowers with white petals and deep purple veins. This perennial also bears thick leaves and stout flower stalks that reach up to 2 feet in height. The wild foxglove prefers dry, acidic soils in partially shady to fully sunny locations. This plant generally performs well in Dallas rock gardens and perennial flowerbeds.
