Grapevines Grapevines are stems that climb on walls and fences by means of specialized supporting organs, called tendrils. Palmately veined leaves arise alternately along the stem. In most varieties, tendrils arise opposite two of every three successive leaves. Flowers, usually greenish, are borne in clusters and have staminate and pistillate flowers sometimes occurring on separate plants. Fruit is borne on 2-year-old canes, which are removed after harvesting the grapes. Grapes are attacked by a great number of insect pests and plant diseases, of which the most common are black rot and downy mildew. See Diseases of Plants. Scientific classification: Grapes belong to the family Vitaceae. The European grape is classified as Vitis vinifera, the northern fox grape as Vitis labrusca, the summer grape as Vitis aestivalis, the riverbank grape as Vitis riparia, and the muscadine grape as Vitis rotundifolia.

Kudzu is a climbing, woody or semi-woody, perennial vine capable of reaching heights of 20 - 30 m (66 - 98 ft) in trees, but also scrambles extensively over lower vegetation. Kudzu is sometimes referred to as "the plant that ate the South", a reference to how kudzu's explosive growth has been most prolific in the southeastern United States due to nearly ideal growing conditions. In all, kudzu infests 20,000 to 30,000 square kilometres of land in the United States and costs around $500 million annually in lost cropland and control costs. It cannot tolerate extremely low freezing temperatures that bring the frost line down through its entire root system; however it does require some cold weather (a solid frost or freeze annually)..
