Hi.
I'm sure a lot of you probably know most of what's in this article about scions, but I didn't. I thought that there might be others that might find this article helpful. It has an introduction explaining the historical origins of some scions, and then has a list of many scion varieties and their advantages / disadvantages. If anyone has any other similar links please post them if you can. Time seems short these days and getting directed to good content is always appreciated. :)
