About 60 species of woody, tendril-climbing vines make up the genus Vitis. These deciduous plants are native primarily to the temperate regions of the Northern Hemisphere. Long cultivated, grapes are economically important fruits for juice, wine, cooking, and the table. Some are also used as ornamental plants. By far the most commonly grown is Vitis vinifera, the European wine grape.
Long flexible climbing stems with grasping tendrils clamber up and over supports; a few Vitis are shrubbier in habit. The stems have shredding bark that peels in strips. The leaves alternate along the stem and are typically toothed and lobed. They often turn brilliant colors in fall.
Grapes vary greatly in hardiness and cultural requirements. Choose plants based on their suitability to local conditions. Full sun, well drained soil, and a large strong supporting structure are generally required. For optimal production, most grape vines need regular care such as annual pruning, consistent pest control, and harvesting. Some types are grafted on rootstocks which impart pest resistance. In addition to being ideal candidates for the culinary garden, grape vines make lovely coverings for arbors, pergolas and walls. (info sorce: Learn2Grow.com)

|Soak the Vitis riparia seeds for 24 hours.
Then cold stratify in the moist peat for 6 weeks.
This will break their dormancy. It creates a cold and moist environment for the seeds. Mixed in seeds with slightly moistened vermiculite or peat, only damp in a ziplock bag. Close zip bag shut and store it in the salad crisper compartment of your refrigerator. If any seeds begin to sprout during the cold stratification, simply remove the seed and plant.
After cold stratification period is over germinate at 20°C, while keeping the peat moist but not wet. Sometimes seeds may take another 12 months to germinate so don't give up thinking you have fewer than satisfactory success rate the first spring. This is nature's way.
