Severn appears in the cultivar index of Edible Apples in Prairie Canada. The source records it as Severn (unknown) and links it to Boughen with a 1930 date, without a clear documented parentage trail [S1]. It is marked CR and treated as a crabapple/applecrab type (fruit under 5 cm), and it is also marked H1, which this document defines as the hardest hardiness class [S1].
Fruit are noted at 3.5 cm, yellow with a crimson wash, soft, and slightly astringent, with overall good flavor [S1]. Severn is described as very early ripening, extremely productive, and heavy bearing at an early age [S1].
Culinary use is strongest for juice and especially sauce, while canning is discouraged as too seedy. It is recommended for short season districts and noted for abundant pollen, with a suggestion it may also be self fruitful [S1]. The source also warns that fruit can become translucent if overripe and is easily damaged by early frosts when left on the tree [S1].
