Sweet red oranges

The opportunity to grow fresh citrus fruit is one of the benefits of living in California's mild climates. One type of citrus gaining popularity is the blood orange. The name comes from the reddish pigment that's present in the flesh and juice, which have a raspberry-like flavor. The intensity of the color varies according to the fruit variety, the tree's location, and the growing temperatures. The flesh usually begins turning red in January, with the rind coloring up later. Named varieties include 'Moro', 'Ruby', 'Sanguinelli', and 'Tarocco'. Of these, 'Tarocco' is sweeter, juicier, and easier to peel, while 'Sanguinelli' (at left), has more intense rind color and berrylike flavor. 'Moro' fruit peaks from January through March but may remain edible longer if left on the tree.

Blood orange trees eventually reach 20 feet tall with an equal width. They need full sun, consistent soil moisture, frost protection, and feeding three times a year with a nitrogen fertilizer. Plant after the danger of frost has passed.
