What are the differences between grapes?

Question

I just got some grapes from a friend who grows them in her back yard. I have had them before, but, was wondering what kind they are? She did not plant them, so she didn't know. They are dark purple. I have always ate them by sucking out the inside and leaving the skin. I thought they were Concord, but, I read that Concord grapes come from New York and surrounding areas. I live in Illinois. Also, can you grow the red type of grapes you get in the grocery store in your back yard? Any info would ge great.

Answer 1

The grapes your friend grows might be concord.  If they can grow in new York why can't they grow in Illinois.  There are quite a few varieties of grapes that you can grow yourself.  Depending on the severity of your winters some might not grow where you live.  A catalog from a mail order nursery should have several varieties to choose from with information about their winter hardiness.

Take a look at this site, it talks about growing grapes in your part of the world.......hope you find the answer.  

Answer 3

Are they seedless?  If so, they might be red flame.  There are many different variaties, so it is difficult to say with limited information.
