Valencia Oranges 
~ Glen Improved Navel Orange 
In many ways the Navel is the most remarkable Orange grown today. It is the Orange which 
standardized the output of California’s citrus orchards, and perhaps it is not too much to say that this 
single variety has been in a large measure responsible for the citrus development in that state. 
Until the last ten years the growing of Navel Oranges in Florida was commercially disappointing on 
account of the tendency of the variety to bear very shy crops of coarse, over-sized fruit. But in 1932, 
William G. Roe, a prominent fruit grower and shipper of Winter Haven, called our attention to a 
strain of the Washington Navel in one of his Polk County groves. These trees are each year producing 
excellent crops of normal-size fruit. Using budwood from this grove, we have been propagating and 
offering nursery trees for several years under the name of Glen Improved Navel. 
Many groves of this improved strain are now in bearing. We have made no attempt to push the 
sale of this variety, preferring rather that the demand for trees should come from the growers them- 
selves, as a result of the fine profits obtamed from the fruit. This demand has increased and every year 
we sell to experienced growers enough trees to plant a total of well over one hundred acres of grove. 
We bud the Navel on Sour Orange and Sweet Seedling roots only; for best results trees should be 
planted in the heavy and more fertile types of soil
