Citrus Variety Information Chart
For each variety we sell, the following table lists that variety's suitability for indoor growing; its minimum tolerable temperature for winter; its bloom and fruiting seasons; and its recommended summer heat level to produce good fruit. Lemons, limes and citrons are most sensitive to frost, while sweet oranges, grapefruit, tangerines and calamondins are intermediate. Kumquats and Owari Mandarin Satsuma are the most frost-tolerant, tolerating temperatures in the low twenties.
Trees grown as houseplants or indoor/outdoor plants are not necessarily subject to these zone limitations. See our heat requirements page for more information on ripening.

Kishu Mandarin
This early ripening mandarin, popular in Japan, produces very sweet, seedless, easy to peel fruit that ripens earlier than Owari Satsuma. Since the fruit is small and soft, it is not grown commercially, but it is becoming a gardener's favorite.
Lemons
While most people will prefer either the mild flavor of Meyer or the classic taste of Eureka, we also offer some unusual varieties for those who wish to experiment.
Improved Meyer Lemon
The gourmet lemon. "Improved" refers to the California state tested, virus-free clone, a collaborative discovery of Joe Grimshaw and Four Winds founder Floyd Dillon in the early 1950's. Very juicy; not as tart as Eureka. Prolific bearer nearly year-round; heaviest in winter. Mature fruit takes on a golden hue.
Eureka Lemon
Produces large crops of lemons annually. Bears all year. Standard market variety. Easy to espalier, fewer thorns than other traditional lemons.
Lisbon Lemon
Fruit quite similar to Eureka. Thornier, dense foliage. Ample year-round crop. Good inland. More resistant to cold than Eureka.
Ponderosa Lemon
Extra large fruit of this citron-lemon hybrid are a favorite among collectors of novelty citrus. Fragrant blooms produce gigantic lemons with many seeds. Tree tends to be thorny and rangy with an open habit. Needs pruning to control shape.
Variegated Pink Lemon
Distinctive green and yellow variegated foliage. Lemons have pink flesh, clear juice and acidic lemon flavor. Fuchsia colored new growth and flower buds. Excellent landscape tree prized more for interesting variegated foliage than for fruit quality and quantity.
Yen Ben Lemon
Similar to Lisbon, this variety is the primary cultivar produced in New Zealand for the Japanese export market. It is smooth skinned with a thin rind and low numbers of seeds. Produces abundantly throughout the year with over 60% of harvestable fruit developing in winter.
Mediterranean Lemons
These selections are some of the most popular lemons grown in the Mediterranean region. They are prized by chefs and citrus connoisseurs for their distinctive flavor and character.
Villafranca Lemon
Said to have been introduced from Sicily around 1875, this variety combines characteristics of both Lisbon and Eureka. Fruit are virtually indistinguishable from Eureka, but winter harvest season corresponds more nearly to Lisbon. Tree shape is similar to Lisbon, but less upright, not as thorny, and with less dense foliage.
Genoa Lemon (Genova)
Italian Lemon - Introduced into California from Genoa Italy in 1875, this variety has similar characteristics to Eureka. In regions of Chile and Argentina where it is grown commercially it is appreciated for its vigorous growth,cold resistance and lush, dense foliage.
Limonero fino Lemon
This winter bearing Spanish variety is a Lisbon type lemon. It is thorny and vigorous, with fruit produced abundantly throughout the tree.
Limettas
Limettas are similar to common lemons but have distinctive characteristics that set them apart.
Millsweet Acidless Limetta
A vigorous tree with lemon-like shape, except that the leaves are more rounded and oval. Blossoms and new leaves are bright purple. Medium-sized, slightly bumpy fruit is yellowish-orange at maturity. The pale yellow interior is low acid with few seeds, thus the name's reference to its sweetness. It flowers primarily in spring and produces fruit in winter which hold well on the tree.
Marrakech Limetta
This highly acidic limonetta is in every other way very similar to Millsweet.
Limes
Limes are one of the most varied groups of all citrus species. They can range widely in shape and form from one another, but all are cold sensitive and need to be protected from frost. Fruit stays green in tropical climates, turns yellow when ripe in California.
Kaffir Lime (Kieffer/Thai/Wild)
Leaves, zest, and juice are used in Thai, Cambodian, and Indonesian cooking. Bumpy fruit.
Mexican Lime (Key)
Small, sometime seedy fruit with genuine tropical flavor year-round. Frost sensitive.

Palestine Sweet Lime
Round, medium-sized juicy yellow fruit. Has less sugar and acid than the Bearss Lime. Similar to sweet limes from Mexico, which also originated from the Mediterranean. With its mild flavor and few seeds, it makes a refreshing, cooling drink.
Rangpur Lime
Tart reddish orange fruit is used like lime, although it is a sour Mandarin from India. The overlap of prolific fruit and purple tinged blooms make this a wonderful ornamental tree. Popular in mixed drinks or simply sliced for ice tea.
Grapefruits
Grapefruits and Pummelos develop the best tasting fruit in areas with warm summer temperatures. The exception is Oroblanco which sweetens without summer heat. In areas with cooler climates, these types of citrus species often tend to have slightly thicker rinds.
Oroblanco Grapefruit
In Israel, known as "Sweetie". Mid winter Oroblanco produces sweet seedless fruit even in areas of low summer heat. Huge, intensely fragrant flowers and attractive glossy foliage.
Rio Red Grapefruit
Popular red-fleshed sport recently introduced from Texas. Needs summer heat to sweeten fruit.
Star Ruby Grapefruit
Tart red fleshed grapefruit is widely grown in Texas and Arizona. We prefer Rio Red because its foliage doesn't get yellow mottling, but some people request Star Ruby because of the name recognition.
Chandler Pummelo
A vigorous large leafed tree with open growth habit. Produces large pink-fleshed fruit which are somewhat larger than standard grapefruit. Heavy producing in the right location, provided sufficient summer heat and frost protection.
Cocktail Grapefruit
Extremely sweet and juicy, this cross between Frua mandarin and pummelo produces delicious, succulent low acid fruit from November to February.

Kumquats
All kumquats have sweet, edible skin and tart flesh, few to no thorns, and extremely fragrant blossoms, in areas with warm to hot summers. They also have exceptional cold-hardiness, making them some of our favorite species of citrus.
Nagami Kumquat
The most widely available kumquat in North America. Olive size and shape, bright orange fruit. Nagami flowers best in areas with warm summers. Late winter or early spring ripening fruit.
Meiwa Kumquat
Fruit is more round than Nagami, with a bit more sweetness. Good candied or in marmalade. Produces best in hotter locations.

Centennial Variegated Kumquat
This variegated sport of a Nagami Kumquat is an attractive finely textured tree with upright growth habit. Variegated pale yellow and cream leaves are complemented by yellow and green striped fruit which become quite large and turn orange at maturity. Ripeness occurs in late winter and fruit holds well on the tree into the summer.
Nordmann Seedless Nagami Kumquat
Clusters of petite orange colored fruit holds well on the tree, making this, like other Kumquats, an attractive ornamental tree. Fragrant flowers in summer, seedless sweet-tart fruit is ready to pick in late winter orearly spring.

Other Interesting Varieties
Each member of this group of varieties does not fall easily into one of the common categories of citrus species. They all have unique characteristics which make them some of our favorites.
Minneola Tangelo
Deep reddish-orange colored fruit in winter. Leave fruit on tree for rich tangerine-like flavor in late spring through summer.
Australian Finger Lime
