Types of Vines
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.
