About this deal
The sweet orange trees ( Citrus sinensis) familiar to us all are hybrids descended from Moroccan tangerine trees ( Citrus tangerina) and Malaysian pomelos ( Citrus maxima). I first came across the practice of preserving immature green bitter oranges in the 1970s when I lived on Crete.
Rather, when the weather warms up again in late spring and early summer, the citrus tends to regreen to protect itself from sunburn.I live in a Mediterranean climate and it's not unusual at all to have last year's crop of oranges and this year's crop of blossoms, or this year's crop of green oranges, on the tree at the same time.
The older ripe oranges get a thicker skin as the weather heats up, and can last through to summer if allowed to remain on the tree. Expert gardener’s tip: A tree’s age and the size of its crop may also influence how quickly its fruit degreens.S., the majority of oranges are grown in California, Florida, Texas, and Arizona, with California edging out Florida for the spot of top orange grower, according to the Produce Blue Book. A small amount of ethylene gas released into the air degrades the peels’ chlorophyll until their color is the sunny orange we’ve come to expect.
