I think this is a good description but maybe with a hint of blueberry too? Definitely on the bland side so I make jams and pies with it!

Juneberries taste like a cross between cherries and almonds, which is not surprising as all are botanical cousins within the rose family (Rosaceae). Baking brings out the berries’ almondy flavor, and Juneberries are excellent in pies, muffins, and other baked goods. Because their flavor is a bit on the bland side, Juneberries in baked goods and jams are best when blended with a tarter fruit, such as mulberry (Morus alba or M. rubra) or black raspberry (Rubus occidentalis), which ripen around the same time as and often grow near Juneberry.
