Description The Eureka lemon tree is a small, virtually thorn-less tree that grows vigorously with an open and spreading form. The Eureka lemons have greenish-yellow flesh color (the variegated varieties flesh color is pink) that is tender, juicy, fine-grained, and has a highly acidic flavor. The Eureka Lemon tree is a drought-tolerant and cold hardy evergreen citrus tree that does well in tropical to subtropical climates and is adaptable to different well-draining soil types and conditions. This lemon lime tree is best grown outdoors in USDA growing zones 8 through 11 and must be protected when temperatures are forecasted to drop below 32F. The Eureka lemon tree can be grown in USDA growing zones 4 to 7 in a pot but should be moved indoors during colder weather when there is any danger of frost or strong winds that may harm the fruit tree. Eureka lemon trees originated from a group of seedlings grown from a fruit of Italian origin in Los Angeles, California that is thought to have been planted in 1858. A few years later, Andrew Boyle and C.R. Workman got their hands on some of the seedlings and selected those that seemed most promising. In 1877 Workman gave a bud from one of the seedlings to a prominent nurseryman from Los Angeles, who propagated and introduced it as Garey’s Eureka (Butterfield, 1963). The Eureka lemon tree is a small, virtually thornless tree that grows vigorously with an open and spreading form. It can grow up to 15 ft in height but can be kept at a desired height through prudent pinching and pruning. These lemon lime trees are ever-bearing and produce medium to small fruit that are mostly elliptical to oblong in shape, with a medium-thick yellow rind. The Eureka lemons have greenish-yellow flesh color (the variegated variety’s flesh color is pink) that is tender, juicy, fine-grained, and has a highly acidic flavor.
