Facts of note: Everyone’s favorite seedless table grape. The world’s leading fresh and raisin variety. Fresh and for raisins. Thin the clusters for larger berries. Loves heat. Thompson grapes were developed in Iran and introduced to California in the 1870s.
Excellent used as an ornamental, for summer shade, arbors or leafy walls. There are 2 basic classes of table grapes.
European varieties are classed as having originated from the cultivar Vitis vinifera and have tight skins, wine–like flavors, high heat requirements for ripening, and are the most common grapes grown in California. Use fresh, dried, and for juices or wine. Susceptible to powdery mildew, they require regular dusting or spraying with sulfur or other mildew control.
American varieties are classified as having originated from the cultivar Vitis labrusca and have Concord–like flavor, moderate heat requirements, and are late blooming and resistant to powdery mildew. They tend to grow well on the East Coast of the U.S.
Both classes may grow successfully in very warm sites at lower elevations, require deep, moderately fertile soils and regular pruning for high quality and production. Self–fertile.
Our vines are self–rooted from cuttings, 1–year old plants, no.1 grade with about 8” of top growth. Sold by individual bare–root vine.
I purchased my Thompson seedless grape vine from Peaceful Valley a couple of years ago. Last year I had one or two small bunches. But this year I have many big, beautful clusters of Thompson seedless grapes! I can't believe how large these clusters are! Just waiting for the sugar content to rise a bit and then will harvest them.Review by Rose (on 9/4/12)
