Prunus cerasus 'Surefire'
Surefire is a large-fruited self-fertile tart cherry. The skin is bright red, and the flesh and juice are also red, making it a "Morello" type tart cherry.
In comparison with Montmorency, Surefire produces larger cherries, but is slightly less productive.

Surefire was so-named partly because it flowers very late, thereby avoiding the early spring frosts which are often a problem for growers in the eastern states. It has a relatively long flowering period for a sour cherry (5 days).
Surefire has become popular with U-pick orchards because the trees grow with an open habit which makes picking by hand easier.

Surefire was the first tart cherry developed at Cornell University, where is was initially known as NY12716. It was released in the 1990s. It is essentially a cross between Morello-type and Montmorency-type sour cherries.
