Narrative

Orig. at the Deschwanden Orchard in Lawai Valley, near Kalaheo, island of Kauai. Introduced in 1967. Unknown seedling selected in 1948; 1953 began testing by Univ. of Hawaii at PoamohoExpt. Farm, Oahu, and Makawao Exp. Farm Maui; first grafted trees fruited in 1958. Scionwood received Oct. 21, 1988 by CR-HIL from CTAHR, Univ. of Hawaii. Nut size: medium, averaging about 80/lb, about .9 inch in dia., shell smooth, medium brown with variable amounts of lighter speckling, kernel 42 - 46% of nut, color light cream, harvest August - November. Tree: moderately vigorous with well formed ascending branch structure so that the tree does not take up as much space as more spreading varieties, strong, medium-wide crotch angles, productive, kernel yield greater than 'Keauhou', 'Ikaika' and 'Kakea' in replicated field testing over 4 years. Not as tolerant to anthracnose as 'Keauhou', but superior in tolerance to 'Ikaika' or 'Kakea'. Named after Keaau Orchard of the Royal Hawaiian Macadamia Nut Co., near Hilo where first comprehensive yield test conducted.
