The fruit on one branch of my in ground Cara Cara is producing fruit with orange flesh. The cultivar Cara Cara originally begun as a limb sport of a Washington Navel orange tree in Venezuela , and has occasionally shown in some trees limb reversion back to the mother variety of Washington Navel orange. Time will tell if this branch continues to produce blond fruit. My tree is presently about 11-feet high and 12 feet wide and 15 to 20 years of age..
