Red Delicious
The Red Delicious is a clone of apple cultigen, now comprising more than 50 cultivars, first recognized in Madison County, Iowa, in 1880. According to the US Apple Association website, it is one of the fifteen most popular apple cultivars in the United States.
Gravenstein
The Gravenstein apple was introduced to western North America in the early 19th century, perhaps by Russian fur traders, who are said to have planted a tree at Fort Ross in 1811. The Gravenstein apple was introduced to the Canadian province of Nova Scotia in the 19th century. Charles Ramage Prescott, the father of the Nova Scotian apple industry, grew Nova Scotia's first Gravenstein trees in his orchard at Acacia Grove. By 1859, Gravenstein trees were commonly cultivated on Nova Scotian farms. The Gravenstein apple is still considered the choicest apple by many Nova Scotians, and the local type is listed on the Ark of Taste.
