Cherries (Prunus spp) Cherries have been a popular tree fruit since the days of the Roman Empire. They were brought to North America by both British settlers and Spanish missionaries. These bright, shiny jewels are one of the first fresh fruits of summer whose ripening is eagerly anticipated by both humans and birds! Sour Cherries (Prunus cerasus) Sour cherries (also known as tart cherries or pie cherries) are more cold hardy than sweet cherries. They bloom later and are simply better suited for colder climates than their sweeter cousins. They are also by nature a smaller, compact tree. Although generally quite care-free and disease resistant, sour cherry trees are not immune to black knot. The health benefits of this fruit are well documented. Trouble falling asleep at night? Sour cherries are a good natural source of melatonin. Drinking several glasses of sour cherry juice daily has been shown to reduce the severity of insomnia and improve overall sleep quality and efficiency. In addition to being a natural sleep aid alternative, research also indicates that sour cherries may help promote heart health and reduce inflammation related to arthritis. 1.25-2m (4-6') bareroot tree
