Article Tools Simply Orange is the trade name for a bottled orange juice product (hopefully the label reveals that it is just orange juice); and those little rotund orbs in bright-lemon-yellow and deep-lime-green found in the produce section of most grocery stores profess to contain the pure juice of the fruits they resemble. For many cooks and diners across the country, this kind of processed product has to suffice. In Southern California, there are so many more choices. Here, citrus can be grown in a wide diversity of other flavors and picked fresh year-round. All citrus have their origins in tropical Asia, but, in Southern California, most will grow well even in interior valleys that experience frost. Microclimate can go a long way to improving flavor in either direction. Lemons and limes will produce fruit of a consistent quality even in the fog zones, but on the coastal strand, plant orange trees in protected south or west-facing sites. Situating them to benefit from reflected heat off walls may really help. Grapefruits need even more heat to be sweet, so site them appropriately, too. There are plenty varieties of lemons and limes, but most people will be satisfied with the most common ones. Starting with lemons, 'Meyer' (and 'Improved Meyer', which is less likely to develop a contagious citrus disease) produces large, juicy fruits nearly year-round. 'Meyer' lemons are not as acidic as regular lemons but are beloved by many for their great aroma and flavor. 'Eureka' is the market favorite.
