One of three (Lee, Osceola, Robinson) resulting from a cross of Clementine mandarin X Orlando tangelo made by Gardner and Bellows of the U.S. Department of Agriculture in Florida in 1942 and released in 1959 (Reece and Gardner, 1959). Produces a medium-small (2¼"–2¾") highly colored fruit. The rind is thin and leathery and peels rather easily. The peel surface is smooth and glossy. The flesh and juice are well colored with high sugar and high acid which is not the best combination for some palates. Seed numbers vary with cross-pollination with 15–25 seeds per fruit when pollinizer varieties are nearby. Cross-pollination is essential to ensure good productivity and to enhance fruit size. Orlando tangelo and Temple appear to be good pollinizers for Osceola. The fruit (and leaves) is susceptible to scab fungus. Tree is not particularly distinctive, being rather upright, densely foliated, and virtually thornless. The variety has not been evaluated on a wide range of rootstocks but should do well on most, especially those that accentuate fruit quality. The tree is fairly cold hardy, but the thin-skinned fruit are not. The leaves (and the fruit) are scab susceptible. Care should be taken when selecting budwood as this variety is susceptible to the viroid disease - cachexia (xyloporosis).
