## Blushed Calville
Blushed Calville is a Russian-origin apple, Malus, listed as a standard apple (fruit 5 cm+) in Prairie Canada references. It appears repeatedly in older prairie and northwestern trial literature for cold-region planting [S1][S2][S4].
## Origin and history
No confirmed breeder, introducer, or formal release year is documented [S1][S4]. The variety is repeatedly treated as Russian and tied to prairie testing, including Rosthern records from the 1930s and broader northwestern and prairie trial lists [S1][S4]. It also appears in older recommendations, including 1890s Minnesota and Brookings trial contexts, which suggests historical nursery and orchard interest [S1][S3].
## Fruit
Sources differ on details but agree on a yellow-based fruit with blush. One source calls it medium with a slight pale blush, another lists it as large yellow fruit in a Prairie directory setting. Shape is described as conic or roundish-conic with angular tendency. Flesh is white, crisp, juicy, and tender [S2][S4]. Quality ratings vary from fair/mellow to good, so it fits better as an older hardy type than a top-tier dessert apple [S1][S2][S4].
## Season, use, and shelf life
Blushed Calville is described as an early-summer apple. Another source gives late-August harvest and about a two-week storage window. It is noted for both dessert and cooking use; flavor and firmness appear usable, though not consistently strong for premium fresh-eating quality [S2][S4][S1].
## Tree, management, and hardiness
Descriptions of tree vigour differ: one source says small and not very vigorous, another says moderately vigorous, but both describe productive trees. Fireblight and hardiness are logged as FB2 H2-3. In this dataset, H2-3 is interpreted as moderately hardy to borderline hardy. The same record sets also treat it as hardy and fruiting in prairie contexts [S1][S4][S6].
## Lineage and broader context
No confirmed parentage is provided in the packet. "Manchester says it is possibly a relative of Yellow Transparent," which is a hypothesis, not a proven cross [S1]. In breeding tables, Blushed Calville appears as named germplasm: it is recorded as a founder at 3.8% in Saskatchewan advanced selections and in Prairie Fruit Project tables with a McIntosh cross and as a female parent count, indicating breeding use rather than a first-generation pedigree record [S4][S5].
