Orange tree Navelina

The most classic of navel oranges, with the typical excrescence.
The fruit is large (180gr +), sweet, with an excellent taste.
The fruit remains on the tree for a long time, and harvesting can be spread over several months, from December to February and beyond.

The tree is vigorous with good fruit production.
This is one of the most cold-hardy of the true orange trees (non-hybrids) and one of the earliest to harvest.
