With seedless grapes, you can enjoy the fruit of the vine without the hassle of large, cumbersome seeds. The majority of table grapes are now grown as seedless varieties; their larger fruit and thin skins make them a quick and easy snack. Thompson is listed as a top cultivar for seedless grapes. And certain varieties, like Saint Theresa and Sommerset seedless grapes, are bred to grow even in the colder climates of Zone 4!
Some seedless grape varieties may develop tiny seeds/vestigial seeds or seed remnants/traces depending on the variety and the climate in which they are grown.
