Cherries are typically categorized in two different ways: sweet or sour. Sour or tart cherries, such as North Star, are the ones used in pies, pastries, cheesecakes, and other desserts. Sweet cherries such as Stella, on the other hand, are best when picked and eaten fresh. And if you needed another reason to plant a cherry tree, there’s nothing more picturesque than one (or many) in bloom!
