The Mexican lime packs a wallop of fragrance and flavor within its thin skin. Famous for its contribution to key lime pies as well as margaritas, daiquiris and mojitos, the Mexican lime also has the most pungent leaves of any citrus.
The Mexican lime is very sensitive to cold temperatures, which limits it to warm tropical and subtropical regions throughout the world. If you plan to grow a key lime tree it should be sheltered from cold north winds. The key lime has a high total heat requirement and needs plenty of direct sunlight.
Mexican limes are frequently grown from seed since it is "true-type". The seeds are poly embryonic, meaning more than one embryo. This results in multiple trees being grown from one seed.
