Introducing Haskap, Japanese Blue Honeysuckle

Abstract

Haskap is a unique form of blue honeysuckle ( Lonicera caeruleaL. var. emphyllocalyx(Maxim.) Nakai ) that has exceptionally fine edible berries. It is native to Hokkaido and northern Honshu in Japan, has only recently been domesticated, and is virtually unknown outside of this region. Research and development of this berry industry in Japan is summarized. Bush and berry characteristics are described. Haskap seeds were introduced to Oregon in 2000, and resultant seedlings have been evaluated in western Oregon and northern Idaho. Plants are environmentally adapted in both locations. With selection of superior cultivars in the current Oregon breeding program, there is excellent potential to develop a new berry crop for this region.
