Switzer is a Russian apple described in A Study of Northwestern Apples as a medium, oblate, regular fruit for September and October use. The bulletin lists it with northern apple cultivars tested for the northwestern United States. Its fruit quality was respected, but tree health was a serious regional problem. [S1]
The fruit is light yellow and almost or wholly covered with bright crimson, with a few obscure white dots. The flesh is snow white, firm, fine grained, rich, spicy, and mildly subacid, with a sweet aftertaste. The source rates it very good. The basin is wide, shallow to nearly flat, and corrugated. It has a closed calyx, a long stem, and a half open clasping core. [S1]
Its season is September and October. The packet gives no storage duration beyond that season and no specific culinary use. [S1]
The main caution is disease susceptibility. A. G. Tuttle and C. G. Patten reported that their Switzer trees had blighted to death. The bulletin concluded that, although many eastern growers esteemed it, Switzer seemed too subject to blight in the northwest. [S1]
No direct parentage, breeder, release date, or hardiness zone is provided. Its cold region relevance comes from its inclusion in a South Dakota Agricultural Experiment Station bulletin on northwestern apples and from its Russian origin. The available source gives a negative regional suitability note, not a hardiness endorsement. [S1]
