Wiki Draft

Cowichan is in a Prairie Canada apple and crabapple directory and is listed as a Preston selection from 1930 [S1]. Its likely origin is an open pollinated Niedzwetzkyana seedling; the source writes this as "op nied" [S1]. Fruit size is about 4 cm and red purple. The source says it is mainly ornamental as a rosy bloom and also can be used for jelly [S1]. Hardiness is rated H3, which the source marks as borderline hardy. It is also marked SC3, meaning scab susceptible [S1]. The entry notes testing at Rosthern in the 1930s and cites Smithfield and F&N. It gives no full release history, flowering or harvest dates, storage life, or formal tree vigor and yield notes [S1].
