Origin / History
Ostrakavis (Ostrakoff × Ben Davis) originated at the Iowa Experiment Station about 1888, as one of several seedlings of the same parentage. "Ostrakavis may serve as a name suggesting the parentage, in case the variety proves valuable under propagation." The variety is noted as interesting as showing that a cross of two sour apples may produce a sweet apple.
