Iowa Blue is an early winter apple distributed from Iowa City, Iowa. The source says it may be an unknown stray from Ohio, not a cultivar with a recorded breeder or parentage. [S1]
The fruit is small and roundish conical, with smooth yellow skin. On the sunny side, it may have a light mottled red blush or a bronze wash. The flesh is white, juicy, mild subacid, and rated good. Its season is early winter. [S1]
The tree is very productive and a strong grower in the nursery and orchard. Young, thrifty trees may have hard, detached, warty excrescences under the bark. [S1]
No direct cold hardiness rating is given. Its distribution from Iowa City and inclusion in a northwestern apple bulletin place it in a northern United States apple context. The source does not state a hardiness zone or winter survival record. [S1]
The available source reports no parentage, breeder, release year, sibling group, or later breeding use. The only origin note is that Iowa Blue was distributed from Iowa City and was thought to be an unknown stray from Ohio. [S1]
