Key limes Facts
Key limes (like Persian limes) are more susceptible to
frost than other citrus fruits. The peak season is
during the summer, June through August, but they are
available year-round from Mexico and Central America.
Most (more than 90%) of the Key Limes increasingly found
in supermarkets are grown in Mexico and Central America;
they are also grown in Texas and California, where they
are known as Mexican limes. Juice content is high, well
over 40%.
