Red River Crab is a crabapple in the genus Malus. South Dakota Extension lists it as a sweet crab in the summer apples section of its home fruit recommendations. The source is a recommendation table, not a cultivar profile. It places Red River Crab among varieties for trial, not among established standard varieties. [S1]
The clearest historical point in this source is geographic. Red River Crab is listed for trial in all three South Dakota fruit growing zones, from the southern border and Black Hills valleys through the protected prairie counties and into the northern two thirds of the state. This gives it clear prairie relevance in the source, though no explicit hardiness zone number is given. [S1]
The source does not give parentage, breeder, institution of origin, fruit description, storage life, or tree habit. It also does not explain the name. For now, Red River Crab is best understood here as a cold climate sweet crabapple that South Dakota Extension considered worth trying across the state in home plantings. [S1]
