I am also in Zone 5 (5a). I am growing Himrod seedles White (Cornel U program). It is 2-years old, small but it may have skinny pencil thick branch that may need pruning. I have not tasted fruit this year because of the birds.
Let me know (PM me) if interested.

PS/Edit: I did not see Jason post before posting.

I have the Reliance seedless and can have a quantity of cuttings if you or anybody else wants. 

Gordenia, I don’t know what spray they use, but I’m sure the information is on the Internet somewhere, such as the Fruit and Orchard Forum of what was Gardenweb. 

 Most grapes grow like weeds here, from my experience. My neighbor has Concord vines that swamp my back fence, and produce wonderful tasting seeded grapes. I’ve planted seeded grapes along the front fence for the neighborhood children to enjoy. Also a row of very crowded seedless grapes for my son. The major problem I’ve found is that the vines over produce, have to be thinned, pruned, and trained. Without thinning (a lot of work), sometimes they are the size of blueberries. Summer Royal has "eaten" one of the trees beside the house. Price, Diamond Muscat, Reliance, Thomcord, and several Muscats are some of my favorites. I grew up on muscadines and prefer the stronger taste of muscat type grapes than bland grocery store grapes. Several vines died in the furnace that was the late summer here last year, or went dormant. It will be interesting to see what sprouts out now.

My grape guru was the late Lon Rombough who wrote The Grape Grower and sold me most of my cuttings. He referred me to a great nursery for grafted vines. I think his family still maintains his website: http://www.bunchgrapes.com/  . It has some of the best grape information anywhere for cooler climates.
