The Currants look delicious!
When I first moved to Georgia I was advised to not plant Currants here. As beautiful as they are, the Red Currants cannot be planted in parts of some states. It is an alternate/intermediate host for the disease known as White Pine Blister Rust (wpbr). While the wpbr doesn't do much damage to the Currants, the disease can destroy Pine trees.
Check local restrictions before planting in your area or the local population of White Pine trees could be in danger; look for wpbr restistant varieties. There are efforts to breed wpbr resistant Pine trees and Currants. In this article you can read a better explanation.
