Lemons are believed to have originated in northeastern India, northern Myanmar, and China as a natural hybrid between the citron and a sour, mandarin-like orange, making the common lemon, scientifically classified as Citrus limon, a hybrid fruit rather than a truly wild species in its own right. Spain has grown into one of the largest lemon producers in the world today, harvesting several million tons annually, an output driven largely by the country’s massive Fino and Verna plantings dedicated to both the fresh and processing markets.
The United States, primarily through California and Arizona, has developed its own extensive lineup of named lemon varieties over the past century and a half, many arising as spontaneous bud mutations discovered on existing Eureka and Lisbon trees rather than through deliberate crossbreeding.
Beyond the familiar Eureka and Lisbon lemons found in most grocery stores, the broader lemon family includes the sweet, thin-skinned Meyer lemon prized by home cooks, giant citron-descended varieties weighing several pounds each, bumpy-skinned rough lemons grown mostly as rootstock, and regional South Asian types that rarely leave the markets where they are grown.
This article explores 55 types of lemons, spanning major commercial cultivars, historic regional varieties, and unusual botanical relatives from citrus-growing regions around the world.
Types of Lemon Varieties
Eureka Lemon
The Eureka lemon is one of the two foundational commercial lemon varieties grown worldwide, first raised from seedlings of Italian fruit in Los Angeles, California, in the 1850s and later propagated commercially under the name Garey’s Eureka. This variety produces medium-small, elliptical fruit with a finely pitted rind, a short nipple at the blossom end, and pale greenish-yellow, highly acidic flesh.
Eureka trees are virtually thornless and strongly everbearing, producing fruit at the ends of long branches almost continuously throughout the year rather than in a single concentrated harvest. This lemon remains the dominant fresh-market variety in California and most lemon-growing countries outside the Mediterranean basin.
Allen Eureka
Allen Eureka is one of the most widely planted clonal selections within the Eureka lemon family, valued by California nurserymen for its consistent fruit quality and reliable production. This variety produces fruit essentially identical to standard Eureka in flavor and appearance, distinguished mainly by subtle differences in tree vigor noted by growers over generations of propagation.
Allen Eureka has remained one of the preferred budwood sources for new Eureka plantings throughout California’s commercial lemon industry. This lemon illustrates how much of Eureka’s continued dominance rests on a handful of carefully maintained clonal selections rather than the original seedling tree itself.
Cascade Eureka
Cascade is another prominent clonal selection of the Eureka lemon, recognized alongside Allen, Cook, and Ross as one of the varieties most commonly recommended by California nurseries. This variety produces medium-small, juicy fruit consistent with the broader Eureka category, prized for dependable year-round cropping.
Cascade Eureka trees have been propagated commercially for their steady performance under a range of California growing conditions. This lemon remains part of the small group of named Eureka clones that collectively supply the bulk of the state’s fresh lemon budwood.
Cook Eureka
Cook Eureka is a nucellar clonal selection of the standard Eureka lemon, developed specifically to provide growers with virus-free budwood free of the diseases that had accumulated in older Eureka trees over decades of grafting. This variety produces fruit essentially identical to standard Eureka in flavor, size, and rind texture.
Cook Eureka has been used as a preferred budwood source in several major lemon-growing states, including limited plantings in Florida. This lemon represents an important disease-management advancement within the Eureka lineage rather than a distinct new flavor profile.
Ross Eureka
Ross Eureka, often marketed alongside the closely related Taylor selection, is a clonal Eureka variety recognized for good fruit size and reliable cropping under California conditions. This variety maintains the classic elliptical shape, finely pitted rind, and highly acidic pale flesh associated with the broader Eureka category.
Ross Eureka trees have contributed to the diversity of budwood available to California lemon growers seeking specific tree performance traits. This lemon remains one of several minor but well-documented selections that make up the modern commercial Eureka lineup.
Frost Eureka
Frost Eureka refers to a nucellar, virus-free strain of the standard Eureka lemon developed through a disease-elimination program at the University of California, aimed at removing viral diseases that had built up in older Eureka budwood. This variety produces fruit essentially identical to standard Eureka in taste and appearance, with the primary benefit being improved tree health and vigor.
Frost Eureka became a preferred source for establishing new, disease-free Eureka orchards throughout California starting in the mid-20th century. This lemon represents a behind-the-scenes horticultural advancement rather than a distinct new fruit type.
Variegated Pink Eureka
Variegated Pink Eureka, also called the pink-fleshed Eureka lemon, is a striking mutation discovered as a sport on an ordinary Eureka tree in Burbank, California, in 1931. This variety produces fruit with pink flesh, a green-striped rind while ripening, and variegated foliage that makes the tree itself an ornamental curiosity.
Variegated Pink Eureka juice turns a pale pink shade when squeezed, making it a popular novelty choice for pink lemonade and specialty culinary presentations. This lemon remains a specialty item grown on a limited scale compared to standard Eureka plantings.
Lisbon Lemon
The Lisbon lemon is the second of the two foundational commercial lemon varieties, originally developed in Portugal and now grown extensively in California, Arizona, Australia, Uruguay, and Argentina. This variety produces medium to large, elliptical to oblong fruit with a thicker, rougher rind than Eureka and pale-yellow, mostly seedless flesh.
Lisbon trees are notably vigorous and upright, with dense foliage and long thorns, and are considerably more resistant to frost, wind, and high heat than Eureka trees. This lemon remains especially important in Arizona and other regions where its hardiness gives it an advantage over its main commercial rival.
Prior Lisbon
Prior Lisbon is a long-established clonal selection within the Lisbon lemon family, historically recognized for good fruit quality and dependable production. This variety produces fruit consistent with the broader Lisbon category, distinguished mainly by grower-noted differences in tree performance.
