Northline and Honeywood are Amelanchier alnifolia, and are no doubt the best choice if you live in Saskatchewan or Minnesota. They are a commercial crop in Canada.
They had mildew problems in Kentucky. But since we have Amelanchier lavies, Amelanchier Canadensis, Amelanchier stolonifera, and Amelanchier arborea in our hills and mountains, the natives or the hybrids are better in Mid-Atlantic or Southern states.
Most of the “apple serviceberry” hybrids are a cross of Amelanchier arborea x Amelanchier lavies (the Appalachian serviceberry). “Amelanchier x grandiflora” is the designation.
There are at least half a dozen others, including Asiatic serviceberry. And a neighbor of mine has an Amelanchier lavies that is 72 feet tall…but even that isn’t a record.
