We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
Some varieties of Serviceberry, more commonly known as Shadbush up here because it blooms during the Shad run, grow in most parts of the US and southern Canada. Some grow as shrubs, some as small trees. If you spend any time tramping outdoors, you will see them.
Some varieties are used as landscape plantings (I have used them) but most grow wild, especially in brushy edges.
The berries look somewhat like blueberries, and range from red to purple to black.
Depending on the variety, the berries can be sour or sweet. All are edible raw, and you can make jam with them too.
Serviceberry is not to be confused with the Huckleberry, also a common wild plant. Huckleberry is a common meadow edge plant.
I think these are what we call 'Saskatoon' berries here in Alberta Canada.
I have many happy memories of gathering big bowls of them with my two brothers, for our mother, who would make jam and pies. https://www.acanadianfoodie.com/2011/08/18/traditional-canadian-prairie-saskatoon-berry-pie/
