Alfred is a blackberry offered for northern planting. Daniels Nursery described it as the hardiest of the better blackberries and probably the best blackberry for home and commercial plantings in the North. The same entry says its popularity was well deserved. This places Alfred among the better regarded hardy blackberries in mid 20th century nursery trade literature. [S2]
The packet does not preserve a breeder, place of origin, release date, or parentage for Alfred. By 1937, it was established enough to appear in a nursery price table as both a one year standard plant and a two year heavy plant. This suggests it was sold in more than one grade before the later Daniels description. [S1]
The sources describe plant performance more than berry appearance. Daniels calls Alfred vigorous, very productive, and the best in quality among the better blackberries, but gives no detailed account of berry size, color, season, or storage. [S2]
Hardiness is the clearest trait attached to Alfred in these sources. Daniels explicitly presents it as the hardiest of the better blackberries and recommends it for northern use, while the broader catalog context targets growers in northern regions of the United States and Canada. [S2]
The surviving evidence remembers Alfred less for a detailed fruit portrait than for its reputation: hardy, vigorous, productive, and good enough in quality for commercial as well as home planting in the North. [S2]
