Timeline of United States discoveries
The Red Delicious is a clone of apple cultigen, now comprising more than 50 cultivars. The Red Delicious apple was discovered in 1875 by Jesse Hiatt on his farm in Peru, Iowa. Believing that the seedling was nothing more than nuisance. After chopping down the tree three times, Hiatt decided to let the tree grow and eventually, it produced an unknown and new harvest of red apples. Hiatt would eventually sell the rights to this type of apple to the Stark Brothers Nurseries and Orchards who renamed it the Red Delicious.
Macoun apple
'Macoun' apples are a cross between the 'McIntosh' and 'Jersey Black' cultivars. The Macoun ("Ma-cown," after the variety's namesake, Canadian horticulturalist W.T. Macoun, but sometimes also pronounced either "Ma-coon" or "McCowan") was developed at the New York State Agricultural Experiment Station in Geneva, by Richard Wellington. It was first introduced in 1923, and is an eating apple. This apple is excellent for making the European style apple pies because it doesn't break down during cooking and remains firm. Macouns are also very popular at roadside stands and pick-your-own farms. Availability is generally October through November.
