Parentage unknown but is of type as might be expected from a Information Network - (GRIN). [Online Database]. Logan x Lucretia cross; some consider Himalaya as the female parent; seedling http://www.ars-grin.gov/cgi- grown about 1920; bushes transplanted to Anaheim, California, in the late 1920s. bin/npgs/acc/display.pl?1448308 Fruit: black; flavor very fine but not as sweet as Young; size extremely large, 1.25 inches or more long; rather soft; aroma distinct; covered with a dusty bloom; bears through August in some areas, ripens 1 week before Young. Bush: trailing (dewberry type); more vigorous that Young; high yields. In California, Boysen and Nectar are different varieties. -- Brooks and Olmo Register of Fruit and Nut Varieties. Fruit black, flavor very fine, very large. Midseason, vigorous, yields to 4Tons/Acre in Oregon."
