As far as i know, all the sugarloafs where originally grown on east Hawaii, in Kapoho, not Kona or Kauai. The fellow who first introduced the sugarloaf to Hawaii told me it was a type of pineapple he brought in from Mexico. It's possible there are some mutations and some selections have been made along the way. Not surprising as the sugarloaf was introduced to Kapoho over 30 years ago.
