Although it is not a berry it is considered aggregate it's bright red color makes it easy to spot and it's wonderful sweet tart taste makes it hard to gather. I tend to eat more than I gather. Three cups can be enough for a pie or muffins,Jam, or you can eat them in only a few minutes. It does not seem to have a preference to shade or sun although some sun adds to the size and sweetness. We are around 3000 ft. though I have seen them at higher elevations.It is a non native coming from China through Europe. Considered by some to be invasive. One of my favorite berries.Prefers slopes with good drainage and woodsy soil.
