I ordered mine from StarkBros, who'll ship to your area and replace any plants that die within the first year.
Unfortunately, StarkBros aronia berries are more expensive than when I ordered mine two years ago. StarkBros is a tad expensive, but has some great deals whenever they've got a sale going due to overstock or whatever.
I haven't tasted mine yet (the first bush of five produced this year, but I pulled them off to let the bush grow better). I'm hoping to jar some
fruit juice and make wine out of them. As a kid two decades ago, we used to buy Aronia Berry Juice from Costco by the gallon, and my whole family loved it as a superior taste relative to cranberry-based juices or concord grape juice, but I'm not sure what species Costco used, or if they mixed them with other juices. That was before Aronia berries became a health fad.
