Cooper is a hardy hybrid cherry listed by Fruit Growers Service Co. in its 1937 northern fruit catalog. The catalog calls it a seedling of Compass cherry and cites Prof. A. F. Yeager of the North Dakota Agricultural College. [S1]
The plant is described as somewhat like Compass cherry, but with much larger fruit. The ripe fruit is round and pink. [S1]
Its main reported use is canning. The catalog says the fruit has a thin peeling that becomes hard to notice when cooked. It produces a canned product that, according to the source, is closer to white sweet cherry than any other cherry it knew. [S1]
The page lists Cooper among hardy cherries for northern planting, alongside Sapa, Oka, Compass, and Mordena. It also appears in a sidebar for two new cherries offered that year, with stock described as very limited. [S1]
The available source gives no direct zone rating, release year, disease notes, or detailed hardiness trial record. Its cold-climate relevance comes from its placement in a northern hardy fruit catalog and from its Compass cherry parentage. [S1]
