All 150+ citrus cultivars we track, in one place.

The original Mediterranean clementine, small and richly flavored; like all clementines it goes seedy if cross-pollinated, so block isolation is the whole game.

A cold-tolerant orange-mandarin-tangelo hybrid released for Florida juice; legally classed as an orange, early and somewhat hardier than a true sweet orange.

A satsuma hybrid (Texas A&M) selected for cold hardiness near 12F, pushing the satsuma range a little colder; seedless and easy-peel.

A California Washington-type navel selection chosen for size and early production; field behavior tracks the navel class.

A tiny native Australian lime notable for real drought and frost tolerance (to about 20F), unusual among limes; a bushtucker and breeding specialty.

The 'citrus caviar': finger-shaped fruit whose vesicles burst like beads, in colors from green to deep red. A high-value chef specialty; UCR released 18 improved selections.

A Brazilian navel selection, smaller-fruited and productive; the navel standard in parts of South America.

The seedless commercial lime of grocery stores: larger and less acidic than Key lime, very tender at about 30F. The fresh-market and bar standard.

A Florida Lisbon-type lemon (distinct from Bearss lime) valued for oil-rich aromatic rind in the humid Southeast.

The aromatic sour orange of Earl Grey tea and perfumery, grown almost entirely for its essential oil. Calabria's signature; the fruit itself is not eaten.

An Australian finger-lime x Rangpur hybrid with striking red rind and flesh; a high-value chef and specialty fruit, hardier than a true lime.

A cold-hardy sweet-tart grapefruit-type, much hardier than true grapefruit and far less bitter. The honest grapefruit answer for a cold-hardy planting, where real grapefruit needs heat the Mid-Atlantic does not have.

The second-most-planted Gulf satsuma after Owari, valued for ripening a touch earlier. A practical choice where the season is short and the first freeze comes soon.

An early-ripening Gulf-belt satsuma selection that beats Owari to market by weeks; seedless and easy-peel.

The fingered citron, split into fragrant tentacle-like sections with no flesh or juice; used for zest, candying, and as a fragrant ornamental.

A kumquat-by-mandarin cross, hardy to about 22F, that fruits year-round and works like a lime or lemon in the kitchen. As much houseplant as crop: prolific, ornamental, and the most forgiving of this set to keep in a pot.

A pink-fleshed navel sport with a sweet, berry-like, low-acid flavor that commands a fresh-market premium. Lycopene-pigmented, not blood-orange anthocyanin.

A variegated kumquat with striped fruit and strong ornamental appeal, eaten whole like Nagami; a patio and specialty plant.

The leading commercial pummelo: huge, thick-rinded, with sweet pink firm flesh eaten in segments. Mild and non-bitter, a festival fruit across Asia.

Among the hardiest true mandarins, taking it well into the single digits, which is why it shows up constantly in cold-hardy breeding. The catch is seeds: it is very seedy, so it earns its place on hardiness and parentage, not eating convenience.

A very cold-hardy citrange-type hybrid used mainly in cold-hardy breeding and as an ornamental; carries trifoliate flavor, not a fresh fruit.

The self-incompatible exception in this set. It needs a cross-pollinizer for a full crop, and that cross-pollination is exactly what makes it seedy. Marginal on both cold and the heat it wants to size and sweeten; included to exercise the inverted pollination rule in both directions.

The leading commercial clementine: easy-peel, sweet, and SEEDLESS ONLY WHEN ISOLATED. Sited near a compatible pollen source it sets seeds and loses its market.

A low-acid mandarin-pummelo (not a true grapefruit) that is intensely sweet and juicy but seedy; a winter specialty fruit.

A smooth thick-rinded citron prized for candied peel; the Corsican confectionery citron, almost all fragrant rind and pith.

The historic Christmas tangerine: zipper-skinned and richly flavored, but seedy and alternate-bearing, which is why it gave way to easy-peel seedless types.

A near-seedless early-Valencia type from South Africa, advancing the Valencia window earlier.

The Calabrian commercial citron grown for candied peel (succade) and liqueur; large, thick-rinded, the candying standard.

The original seedy grapefruit, considered the best-flavored for juice; seeds pushed it out of fresh markets but it remains a processing and breeding parent.

A trifoliate-by-grapefruit cross that gives an edible grapefruit substitute hardier than any true grapefruit. Sold for cold-hardy gardens specifically as the grapefruit-flavor option that survives where Marsh cannot.

The latest commercial mandarin, holding into summer with rich flavor and freckled rind; seedy and cross-dependent, a season-ending niche.

The ritual citron of the Jewish festival of Sukkot, grown to exacting standards; almost all rind and pith, intensely fragrant, very cold-tender.

The supermarket lemon standard: nearly thornless, fruiting year-round, the California fresh-market and culinary default.

Marketed as Pink Lemonade: variegated foliage and fruit with pink flesh and nearly clear juice; novelty and ornamental.

The lime-kumquat cross listed in the specialty group as well as limes: a hardy lime substitute eaten rind and all.

An early desert mandarin (clementine x Orlando) that needs cross-pollination to set, and goes seedy when it gets it; a Coachella/desert early type.

A multi-way finger-lime hybrid with caviar-like vesicles and more vigor and tolerance than pure finger lime; a chef specialty in the Australasian-lime group.

The classic Italian lemon group, multiple-blooming (including the prized winter Primofiore and the summer Verdello); the lemon behind Sicilian limoncello and cuisine.

The thin-skinned, very juicy early Spanish lemon, the winter commercial workhorse paired with late Verna.

A red-fleshed, nearly seedless Florida grapefruit with a smooth blushed rind; a fresh-market red type.

An early-coloring Japanese navel with deep rind color, popular for hitting the market ahead of Washington.

Also sold as Changshou; a sweeter, near-thornless kumquat with strong ornamental and container appeal. The friendliest kumquat to handle and to grow on a patio.

An Italian-origin Eureka-type lemon, bushy and productive; grown where its dense habit suits the site.

A late, bumpy-rinded UCR mandarin widely rated among the best-tasting citrus, and seedless despite seedy parents. Holds on the tree into spring.

An early, cold-tolerant-for-an-orange Florida juice variety; productive but pale-juiced, so it is a processing workhorse, not a fresh-market star.

A very late Valencia selection extending the juice-orange season into early summer.

A Japanese pummelo noted for being somewhat hardier and more aromatic than most; large, sweet, segment-eaten.

An intensely sweet tangor (the Florida 'Honey' / 'Murcott') with rich flavor but seeds and a tighter peel; a fresh-market favorite where seeds are tolerated.

The smallest, wild kumquat, mostly seed and rind; primarily ornamental and a hardy breeding parent.

An Ichang papeda hybrid that works as a lemon substitute in places true lemons will not survive. Acid and aromatic; the practical answer to wanting lemon flavor in a cold-hardy planting.

One of the hardiest evergreen citrus in existence and the parent behind yuzu and much of the cold-hardy hybrid world. Harsh and mostly inedible fresh; its value is genetic and aromatic, the backbone of why any of these hybrids hold up to cold.

A Southeast Asian acidless sweet lime juiced locally; a regional specialty in the sweet-lime group.

A necked mandarin-kumquat hybrid (UCR) eaten whole, sweeter than a kumquat with a tangerine note; a specialty fresh fruit.

A very early, elongated lemon-citron hybrid that opens the season; Turkey's leading early lemon.

A sweet thick-rinded Chinese kumquat in the Meiwa group, eaten fresh whole; a regional sweet kumquat.

A yuzu relative used green like sudachi in Japanese cuisine, fairly cold-hardy; an aromatic culinary acid citrus, not eaten fresh.

Grown for its double leaves and bumpy aromatic rind, the foundation of Thai and Southeast Asian cooking; the fruit juice is rarely used.

A small, sweet, very cold-hardy mandarin-type (to about 12F) sold for cold-region dooryard fruit; eaten fresh, with seeds.

The small, intensely aromatic, seedy lime of Key lime pie and authentic cooking; the most cold-tender common citrus and very thorny.

A cold-hardy Louisiana satsuma selection chosen for slightly better cold tolerance than Owari; a Gulf-belt workhorse.

The dominant mandarin of the Indian subcontinent: prolific, rich and aromatic, but seedy. A juice-and-fresh staple at huge scale.

A tiny, intensely sweet seedless mandarin, two bites and no seeds; a specialty premium fruit, historically a Japanese favorite.

An Australian late navel that extends the fresh navel season into spring, holding well on the tree. Part of the late-navel group (with Powell, Chislett, Barnfield) that stretches California supply.

The dominant Cypriot lemon, multiple-blooming and long-cropping; the Eastern Mediterranean commercial type.

An early Florida clementine x Orlando sibling of Nova/Robinson; sweet and early, needs cross-pollination and then seeds.

A lime-kumquat cross hardier than a true lime (to about 22F) that works as a lime substitute with an edible rind; the practical cold-region lime.

Eureka's vigorous, thornier, more cold- and heat-tolerant counterpart, with a more concentrated winter crop; the hardier commercial true lemon.

A Florida Valencia selection long valued for holding quality late on the tree; a historic late juice budline.

An early-season clementine that opens the clementine window; same isolation requirement as the rest of the group.

The white seedless grapefruit standard, the variety the modern grapefruit industry is built on. High heat need: it sizes and sweetens only in hot regions.

A round, very hardy, thorny kumquat that doubles as a landscape plant. Choose Meiwa for eating sweetness; choose Marumi for hardiness and ornament.

The sweet kumquat: rounder and milder than Nagami, the one to eat straight off the tree. Noted alongside Nagami as having genuine small-commercial potential on the Gulf Coast.

Oroblanco's larger UCR sibling: bigger, sweet, low-bitterness pummelo-grapefruit triploid for fresh eating.

A thornless selection of Key lime that keeps the aroma and seediness but is easier to harvest; same tenderness as the species.

The most cold-hardy lemon, a lemon-mandarin hybrid that is sweeter and less acid than a true lemon, but still only semi-hardy at about 20F. In zone 7-8 it is a container plant you protect, not a field tree; included as the borderline case the cold gate should demote, not pass, outdoors.

A lemon-mandarin hybrid, the most cold-hardy 'lemon' at about 20F and sweeter and less acid than a true lemon. The home-grower and chef favorite; semi-hardy, so a container plant in zone 7-8.

A nearly seedless South African Valencia selection, juicy and productive; a fresh-and-juice dual-use late orange.

An early Wase-group satsuma similar to Okitsu. Differentiate on nursery availability; field behavior tracks the satsuma class.

The necked 'Honeybell' tangelo (Duncan grapefruit x Dancy): tart-sweet and aromatic, but self-incompatible, so it needs a pollinizer like Temple or clementine to crop.

A hardier, mal-secco-tolerant Sicilian lemon, less acid than Femminello but valued for disease tolerance in humid groves.

The deepest-pigmented blood orange, needing cool nights to color fully; raspberry-toned and the most dramatic of the blood group.

A sweet-orange-by-trifoliate cross, hardy and juicy but carrying the trifoliate off-note that keeps it out of the fresh-eating tier. Useful for juice and marmalade where hardiness matters more than refinement.

The most cold-hardy edible citrus group, eaten whole, skin and all, with the sweet rind playing against tart flesh. Long on-tree hang turns the tree into its own pantry, and it is compact enough to be a serious container and patio plant.

A very late Brazilian juice orange that extends the processing season past Valencia; a backbone juice type at scale.

An early Washington sport with intense rind color, widely planted in Spain for early fresh markets.

A satsuma-kumquat cross, very cold-hardy (to about 15F), eaten whole with a sweet edible rind; a hardy dooryard fruit and ornamental.

A seedless Nagami-type kumquat: the eat-whole experience without the seeds, a fresh-market improvement on Nagami.

A glossy clementine x Orlando hybrid, sweet and productive; seedless when isolated, seedy near pollen like its clementine parent.

A very early Japanese satsuma with strong color, opening the satsuma season; seedless and a common Gulf and Japanese early type.

An early Wase-group satsuma; one of the cultivars that makes up nearly half of Japanese mikan production. Early maturity is the reason to choose it in a cold-hardy planting.

The dominant California Valencia budline (a nucellar selection), the practical standard behind much of the state's Valencia acreage.

A sister Texas A&M cold-hardy satsuma hybrid to Arctic Frost, similar hardiness with a slightly richer flavor.

An early tangelo (same parents as Minneola) that is juicy and mild but needs cross-pollination; often the pollinizer partner in mixed blocks.

A UCR pummelo-grapefruit triploid that is sweet and bitterness-free, and sweetens with less heat than true grapefruit, widening where a grapefruit-type can grow.

A juicy late tangor from Jamaica, rich and aromatic with a clingy peel; a major export fresh-and-juice fruit in the Caribbean and Mediterranean.

The satsuma-class reference and the commercial Gulf-coast standard. Self-fertile, seedless and the easiest citrus to peel; ripens early enough to beat most fall freezes. If a cold-hardy planting starts anywhere, it starts here.

A richly flavored mandarin hybrid (Minneola x clementine) that eats and juices well; sets best with cross-pollination.

An acidless 'sweet lime' valued in South Asia and the Middle East for a flat, non-acid juice; a specialty and traditional fruit, also a rootstock.

An old early Florida juice orange, largely supplanted by Hamlin but still grown for early processing.

Brazil's dominant juice orange, multiple-blooming and high-yielding; the engine of the world's largest orange-juice industry.

A richly aromatic Florida mid-season orange named for its fragrance; seedy, which limits fresh appeal but not juice quality.

A very late, reliably seedless mandarin that defines the Ojai growing district; mild, sweet, and a spring fresh-market niche.

The cold anchor of the whole library and the parent of most hardy rootstocks. Deciduous, ferociously thorny, and inedible fresh; listed as a scion for completeness and for the rare grower who wants the hardiest possible citrus relation as an ornamental or marmalade source.

The big puffy-skinned 'Chinese Honey' mandarin grown across Asia and Brazil: large, sweet, easy-peel, seedy.

A late Australian navel valued for long on-tree hang and late-season fresh supply. Differentiate from Lane Late and Chislett mostly on timing.

An orange-colored, acid mandarin-lime (not a true lime), hardier than true limes and used both culinarily and as a drought-tolerant rootstock.

A white-fleshed Chinese pummelo widely grown in collections and trials; large, mild, segment-eaten, a pummelo-breeding reference.

A Valencia sport with deeper-colored, lower-acid juice; a processing selection chosen for juice color.

The deep-red Texas grapefruit, marketed as Rio Star, with intense flesh color and reliable cropping; the Rio Grande Valley signature.

An early Florida mandarin (Orlando-derived) that needs a pollinizer; rich and early but seedy and prone to fruit drop.

The original pigmented grapefruit (a Marsh sport) that launched the red-grapefruit market; sweeter and less bitter than white.

A very cold-hardy sweet-orange-by-trifoliate citrange, ornamental and usable for juice/marmalade; carries the trifoliate off-note like the other citranges.

A seedless, very juicy low-acid Spanish orange, a leading juice-and-table variety in Spain.

A late Spanish blood orange with reddish rind and a long hang; the Spanish answer to the Italian Tarocco/Moro pair.

A mild low-acid Pacific pummelo with juicy pink-tinged flesh; a sweet, gentle introduction to the pummelo group.

A premium Japanese tangor with soft thin rind, very high sugar and melting texture, among the most prized fresh mandarins in Japan.

The bitter orange of marmalade and bergamot-adjacent culinary use, and historically the dominant rootstock until CTV decline. Not a dessert fruit.

The Jaffa orange: seedless, easy-peel, thick-rinded and aromatic, the historic export orange of the Eastern Mediterranean.

A late UCR triploid (so reliably seedless) with rich flavor and long hang; part of the Gold trio bred to extend the premium easy-peel season.

An Owari-type satsuma common in the nursery trade. Performs like Owari; choose on availability rather than expecting a meaningful difference in the field.

The protected Sorrento/Amalfi lemon: large, oil-rich, intensely aromatic rind, the lemon of limoncello and Italian coastal cuisine.

The darkest-fleshed grapefruit with the richest flavor, but horticulturally touchy (cold- and herbicide-sensitive, erratic yields); a premium fresh fruit.

A yuzu relative used green and sharply acid, the sour note in Japanese cooking. A culinary specialty, not a dessert fruit; valued for the same reason as yuzu, picked earlier and greener.

A University of Florida hybrid bred for tolerance to HLB and notable for cold hardiness to about 18F. The one cultivar in this set with an explicit, if still emerging, HLB story; sweet-tart and easy to peel.

A deeply colored Florida mandarin needing cross-pollination; productive but seedy in mixed plantings.

A low-acid lime widely juiced in India; mild and sweet rather than sharp, a staple juice citrus on the subcontinent.

A Pacific lime-type used locally; a minor dooryard culinary citrus included for completeness of the acid-lime group.

The early member of the UCR Gold triploid trio: seedless, easy-peel, opening the premium late-mandarin window.

The irradiated seedless version of W. Murcott from UCR, and the dominant easy-peel in California at roughly 29% of acreage. Seedless even near pollen, which is exactly why it displaced cross-sensitive clementines.

The Italian blood orange prized for eating: sweeter and easier to peel than Moro, with partial red pigmentation and outstanding flavor.

A rounder Eustis-sibling limequat, hardier than a true lime and eaten rind-and-all; a compact ornamental and cold-region lime stand-in.

A richly spiced orange-mandarin tangor with intense flavor; seedy and a touch tender, but a classic fresh-eating specialty and a common Minneola pollinizer.

A citrange-by-kumquat cross that is among the hardiest citrus you can actually eat fresh when fully ripe, and use like a lime when not. One of the few that bridges the gap between ornamental hardiness and a usable fruit.

The original pink Marsh sport, lighter-fleshed than Ruby Red; the first pink grapefruit and a Marsh-group fresh type.

A common-orange type that sets and sweetens with less heat than a navel, making it a better choice for coastal and desert-margin sites.

A USDA cold-hardy, disease-tolerant Poncirus hybrid sold both as a vigorous rootstock and a grow-your-own grafting base; resilient where citrus disease and cold both press.

The classic juice orange and the backbone of the processing industry: late, juicy, and able to hang on the tree for months. The summer orange.

A UCR pummelo-blood orange-mandarin hybrid with red, berry-toned flesh and a heart-shaped cross-section; a late specialty fresh fruit.

An acidless (insipid) orange: sweet without the acid bite, a curiosity and specialty fruit rather than a commercial juice type.

A striking variegated Eureka sport with green-striped fruit ripening yellow and pink-tinted flesh; a specialty and ornamental lemon.

Spain's leading late lemon, thick-rinded and holding into summer to bridge the gap after the winter Fino crop.

An Eureka-like lemon historically important in Florida and humid subtropics; denser, thornier foliage than Eureka.

The rich, deeply colored parent of Tango. Excellent eating but cross-pollinates to seeds, so growers either isolate it or plant Tango instead.

The variety that built the California citrus industry: seedless, easy-peel, and the fresh navel standard since 1870. High heat need keeps it out of cool-summer sites.

A late Brazilian juice selection prized for deep juice color and very late maturity; a processing companion to Natal and Valencia.

A very early, high-flavor satsuma increasingly favored for short-season and protected sites. The richest-tasting of the common satsumas in many trials, and it finishes before most freezes arrive.

A thin-skinned, high-juice Lisbon-type lemon dominant in Australia and New Zealand; smooth-rinded and seedless-leaning.

The richest of the UCR Gold trio, bumpy-rinded and seedless; a premium late fresh mandarin.

The cold-hardy citrus a zone 7-8 grower actually gets to keep, hardy to roughly 10F on trifoliate. You do not eat it fresh; you use the rind and juice, whose aroma has no real substitute, across Japanese and Korean cooking. The zest freezes well, which matters because the window is short.

A naturally occurring Ichang papeda x Satsuma hybrid, among the hardiest citrus in cultivation (documented to single digits in zone 7b), grown for yuzu-grade aromatic rind. Seedy; not for fresh eating.
