Hansen White Sweet Clover is a named strain of white sweet clover. The source identifies it as Melilotus alba, the common white sweet clover native to Europe, North Africa, and middle Asia. It is not described as a fruit cultivar. A 1921 northern horticultural catalog presents it as a hardy forage and soil improvement plant. [S1]
Prof. N. E. Hansen raised the strain from seed found growing wild on the dry steppes of Semipalatinsk, Siberia, in 1913. The source links it to Hansen's wider work introducing and selecting plants from severe northern and prairie climates. [S1]
The source gives no edible fruit description. It treats the plant as a white sweet clover strain with possible agricultural value, especially for adding humus to summer fallowed land. Its origin in an 8-inch rainfall climate made it worth comparing with other strains. [S1]
The strongest hardiness claim comes from the University of Saskatchewan at Saskatoon. It reported the Siberian sweet clover as promising because it was the hardiest, earliest, and best strain of white sweet clover. The source gives no USDA zone rating. [S1]
The naming history is clear. Arctic Sweet Clover had been suggested, but the source says Hansen Siberian White Sweet Clover should be kept because it had priority and because the plant was not truly arctic in range. The packet cultivar name, Hansen White Sweet Clover, appears to be a shortened form of this Siberian white sweet clover strain, not a separate fruit cultivar. [S1]
