  A wrought iron arbor tucked into the garden creates a focal point in the yard, an ideal spot to grow a flowering, creeping plant. Grown in a wide range of bloom colors, shapes and sizes, plants such as vines creeping up and over the arbor create a vertical garden and strong architectural line. They also create shade and privacy below the arbor for a vibrant, lush display.
  
  

Carolina Jasmine

• Carolina jasmine (Gelsemium sempervirens) is an evergreen vine with a moderate to rapid growth rate and twining, wiry stems. It grows 10 to 20 feet in height, creating an ideal plant to grow over a wrought iron arbor in any shape or size. Carolina jasmine produces trumpet-shaped, yellow flowers that are fragrant and emerge in spring. The evergreen foliage on Carolina jasmine vines bronzes in winter for a vibrant garden display. Hardy, Carolina jasmine is both wind- and drought-tolerant. It grows best in full sun to part shade and well-drained, nutrient-rich soil. Grow Carolina jasmine in USDA Plant Hardiness Zones 7 to 9.
  
  

Cross Vine

• Cross vine (Bignonia capreolata) is a woody, semi-evergreen vine that climbs with tendrils. It has a vigorous growth rate and grows 35 to 50 feet tall and has a spread of 6 to 9 feet wide. Cross vines bear orange to red, trumpet-shaped flowers that emerge in spring to rapidly cover structures like wrought iron arbors with their attractive flowers and foliage. The fragrant flowers on cross vines are 2 inches long and are followed by the green, pod-like seed capsules that grow up to 7 inches long. The lanceolate to oblong, dark green leaves casts a red to purple color in fall. Cross vines grow best in full sun to part shade although the best flower production takes place in full sun and well-drained soil. Grow cross vines in USDA Plant Hardiness Zones 5 to 9.
  
  

Wild Passion Flower

• Wild passion flower (Passiflora incarnata) is a rapidly growing, climbing vine that bears creeping tendrils. It grows 6 to 8 feet tall and 3 to 6 feet wide and produces dark green, three-lobed leaves. The fringed flowers on wild passion flower vines have white petals and sepals with a center crown made up of pink and purple filaments. The fragrant, summer-blooming wild passion flowers are followed by the egg-shaped, edible fruit called maypops that can be eaten fresh off the vine or used to make jelly. Wild passion flower vines grow best in full sun to part shade and well-drained soil. Grow wild passion flower vines in USDA Plant Hardiness Zones 5 to 9.
