Peterhof is a Russian apple cultivar recorded in N.E. Hansen's 1902 survey of northwestern apples. The specimens came from F. I. Harris of LaCrescent, Minnesota, so the cultivar was being evaluated in the Upper Midwest, though its origin is listed as Russia. [S1]
The available source gives no parentage, breeder, release year, or testing code for Peterhof. Hansen presents it as an introduced apple, not as a named seedling from a documented breeding program. [S1]
The fruit is small and oblong conic, with an irregular, angular, ribbed shape. The skin is polished pale waxen yellow, almost fully covered with brilliant dark red, with clear splashes and stripes of dark crimson. Hansen calls it a beautiful fruit. [S1]
The flesh is white and strongly stained with red. It is moderately juicy and subacid, with only fair quality. The season is August. [S1]
The source gives detailed identification traits, not a grower tree description. Peterhof has obscure minute white dots, a regular acuminate cavity with a large radiating russet patch, a shallow almost flat basin, a closed calyx, a conical tube, marginal stamens, ovate cells, and small plump seeds. [S1]
No hardiness zone is stated. Its Russian origin and inclusion in a South Dakota Agricultural Experiment Station bulletin on northwestern apples suggest cold climate interest, but the Peterhof entry does not document winter survival or a zone rating. [S1]
Peterhof belongs here as a historically recorded Russian apple in the broader Malus cultivar record. Its clearest preserved trait is visual: a small, ribbed apple with pale yellow ground color nearly hidden by dark red and crimson striping. [S1]
