October - January Hamlin is the most widely grown early sweet orange in Florida and the tree among the most cold tolerant.
Several selection are available.
Its earliness makes much of its harvest possible before the onset of winter freezes in Florida. Because of its high yields, Hamlin is the most productive on the basis of pounds of solids per acre even though solids per box are lower than for Pineapple and Valencia. Its juice color score is also low, particularly on lemon-type rootstocks so the juice is blended with that of other varieties to meet color standards. The fruit of this variety will develop a good natural color break. Small fruit size can be a problem for the fresh fruit market, particularly during heavy crop years and when soil potassium levels are inadequate.
