Tiesenhausen is a Russian-origin apple described in N. E. Hansen's A Study of Northwestern Apples. The fruit is large, usually oblong conic and sometimes roundish conic. It has green skin, fine green dots, and some net veined russeting. Hansen described it from specimens supplied by F. J. Peterson of Waconia, Minnesota. [S1]
The available source gives no breeder, release year, or formal introduction program for Tiesenhausen. Hansen places it with Russian apple material described for northwestern use, but this record is a descriptive entry, not a breeding history. [S1]
The fruit has white, juicy flesh with a sprightly acid flavor and only fair dessert quality. Its listed use is culinary, so this source presents it as a kitchen apple more than a fresh eating apple. The cavity is very shallow and nearly flat, with a very short stem about one half inch long. The basin is shallow and corrugated, the calyx is closed, and the core is closed with elliptical cells. Season is late fall. [S1]
A later diagnostic list in the same bulletin places Tiesenhausen among green, yellow, or white apples, with white or whitish flesh, a conical tube, marginal stamens, and a very short stem. This supports the main entry and shows Hansen also used Tiesenhausen as an example in keyed cultivar lists. [S1]
The source gives no direct zone rating, winter survival statement, or tree habit description. Its Russian origin and inclusion in a northwestern apple bulletin make it relevant to northern apple history, but the available evidence does not support a stronger hardiness claim. [S1]
One descriptor is uncertain: one noisy extracted line describes the tube as funnel shaped, while the stronger narrative entry and keyed list describe it as conical. [S1]
