It is indeed Amelanchier, a common shrub or small tree in my area (western NC, USA) called Sarvice (Service Berry), and other varieties and species of it are called "Juneberry" or "Shadbush" outside of the mountains, as it blooms when the Shad run in the spring (early!) and fruits in June.

artdeco, it's hard for me to see the size and shape of the berries, as it's on the side of this house and I've only seen it from the street. It appears to be covered in berries and looks to be about 6 feet tall. The shape is hard to explain, the more I look at it, the more is appears to be a little stragely rather than dense and compact. It probably is a winterberry bush. From what I've read, winterberries aren't really a favorite of the birds, at least not until late in the winter when all else has been eaten. I love the looks and color of the shrub I've been seeing, the berries are so bright, you can see them from down the street. It almost looks like the shrub is covered with bright red flowers. I'm pretty sure I will purchase a male and female in the spring. I will have to investigate the best ones to get for zone 5. Linda

Ok, it looks like the first one is Wahoo. The 2nd one I so want to be a native Bittersweet, not the oriental substitute. I took some more photos today. They are vining around some Sumac. Bittersweet Bittersweet Any other opinions??

While you are waiting for an expert to respond, I'll throw in my two cents: My intial take is that it is not a highbush blueberry (Vaccinium corymbosum), because of the color of the berries. V. corymbosum also has an interesting bark - it looks like a dark brown or tan bark has been stripped away in segments to show a lighter underbark -- there is something muscular or shredded looking about it. But I'm not sure this isn't true for other members of the family. The location is right for V. corymbosum, but it's also right for other berry-making plants, such as various native and non-native buckthorns (the non-natives are invasive) and the huckleberries. I believe buckthorns are toothless (at least the European is), while blueberries and huckleberries have toothed leaves. The general rule with the color of blueberries and huckleberries is that blueberries are more blue than black and huckleberries are more black than blue. Also, blueberry seeds are numerous and tiny, so you don't notice them when you eat the berry, while huckleberries (at least Gaylussacia baccata) have a small number of larger seeds, and you notice them. I live in eastern Mass. and have noticed in some wetter (but not swampy) areas, a lot of dangleberry shrubs (Gaylussacia frondosa?), a huckleberry, that may match your plant: black berries, toothed leaves (I think) and larger than some of the smaller huckleberries and blueberries (I think - wasn't clear from description). My only question is the wavy white line on the berries, which doesn't seem to fit with my understanding of either blueberries or huckleberries. As I said, I'm not an expert, so I hope someone will jump in and correct me if I've led you wrong. -- wd
