Roxanna is a named apple cultivar recorded in N. E. Hansen's 1902 bulletin A Study of Northwestern Apples. The source gives its origin as Wisconsin and describes it as a winter apple with medium fruit. It does not give parentage, breeder, release date, or nursery introduction history. [S1]
The fruit is conical, irregular, and angular. The skin is yellow, but almost fully covered with fine crimson and carmine splashes. The flesh is white and fine grained, with mild subacid flavor, a sweet aftertaste, and a rating of very good. [S1]
Hansen gives detailed morphology for Roxanna. It has a regular, slightly russeted, acute cavity; a short stem; a very shallow, narrow, wrinkled basin; a half open calyx; a closed clasping core; very plump seeds; and ovate cells. A later classification line places it among striped apples with a conical tube, marginal stamens, and a very shallow, narrow basin. [S1]
Its season is listed as winter. The source does not state storage duration beyond that class. It also does not give culinary use, tree habit, productivity, disease behavior, or hardiness performance. Because the bulletin covers northwestern apples and hardy northern material, Roxanna belongs in that evaluation context, but the source gives no direct zone or winter survival claim for this cultivar. [S1]
