These go way beyond what you’ll see in local grocery stores.

These fruits don’t just help you broaden your taste horizons. They let you make environmentally conscious food choices too. A plant-based diet with a variety of fruits helps both animals and the planet. The juicy sweetness of Osteen Mangoes and the tart flavor of Oregon Grape give you amazing taste experiences and health benefits. You might be a fruit lover or a food explorer looking to try new things. This piece shows you all the O-fruit varieties that could become your new favorites.

Citrus Fruits That Start With O

The citrus family includes some of the most vibrant and nutritious fruits that start with O. These fruits combine unique flavors with amazing health benefits. Let’s explore everything from common varieties to rare gems that deserve a spot in your fruit bowl.

Orange: The classic vitamin C powerhouse

Oranges lead the pack as the quintessential vitamin C powerhouse among O-starting fruits. A single orange packs 70-90 milligrams of vitamin C, which helps you achieve your daily required dose. This bright, round fruit originated in Southeast Asia and has become a worldwide favorite thanks to its refreshing taste and impressive nutritional profile. The fruit’s fiber supports digestive health while its antioxidants help reduce inflammation throughout the body.

Orangelo: A grapefruit-orange hybrid

The orangelo, which Spanish speakers call “chironja,” is a fascinating hybrid between grapefruit and orange. Carlos G. Moscoso from the University of Puerto Rico found these unusually large, bright yellow fruits growing on shade trees in Puerto Rico’s coffee plantations back in 1956. The fruit has a round to pear shape with 9-13 segments and peels more easily than typical grapefruits. Its distinctive flavor blends orange sweetness with subtle grapefruit notes, without overwhelming bitterness.

Oroblanco: A sweeter take on grapefruit

“White gold” in Spanish, the oroblanco is perfect for people who find regular grapefruits too bitter. Scientists created this hybrid by crossing an acidless pomelo with Marsh grapefruit. The fruit has a thick, smooth peel that stays green long after ripening, turning yellow only weeks later. The oroblanco lacks the usual grapefruit bitterness while keeping a sweet, mild taste. These fruits need less heat than other grapefruit varieties and ripen earlier, which makes them ideal for moderate climates.

Ōgonkan: Japan’s golden citrus gem

The sort of thing I love about Ōgonkan is its brilliant yellow color and compact size. These little fruits are just 4-5 cm across and weigh between 60-80 grams. Small but mighty, they pack impressive flavor – sweet with balanced acidity. Japan’s Kanagawa Prefecture produces 68% of all Ōgonkan, with Shizuoka, Ehime, and Kōchi Prefectures growing the rest. You can find these winter-to-spring treats from February through April.

Ortanique: A unique orange-tangerine mix

The ortanique naturally combines orange and tangerine traits in one fruit. Its clever name comes from “or” (orange), “tan” (tangerine), and “ique” (unique). This Jamaican discovery yields medium-sized fruits with pebbled, dark orange skin covering super juicy, orange flesh. The fruit’s rich, sweet flavor sets it apart from regular oranges. Late-season maturity and good tree-holding ability make ortaniques great for extended harvests.

Owari Satsuma: Easy-peel mandarin favorite

Owari Satsuma tops the list of popular Satsuma mandarin varieties in the United States. This Japanese variety produces medium-sized fruits with smooth, thin orange skin that peels like a dream – perfect for snacking anywhere. Inside, you’ll find tender, juicy, seedless segments with a mild, pleasant taste. The tree handles cold weather well, though harvested fruits store better than those left on branches. California growers usually harvest their Owari Satsumas in December and January.

Berries and Small Fruits You Might Not Know

A fascinating collection of berries and small fruits starting with O exists beyond the familiar citrus world. These gems have extraordinary flavors and unique traits that make them perfect for culinary adventures and health benefits.

Olallieberry: A blackberry-raspberry hybrid

The Olallieberry is an exceptional hybrid fruit created in 1935 by George Waldo through a USDA-ARS breeding program with Oregon State University. This dark purple-black berry came from crossing the ‘Black Logan’ blackberry with the youngberry. Many people call it a perfect balance of sweetness and tartness. Scientists first picked it in 1937 and officially released it in 1950. The Olallieberry now has loyal fans, especially along California’s central coast.

The berry’s juicy texture and bold flavor reminds people of blackberry jam with hints of cassis and plums. It works great both fresh and in cooking. These berries pack plenty of vitamin A, fiber, vitamin C, and other nutrients like iron, calcium, and potassium. You should eat them quickly after buying or freeze them for up to three months because they spoil fast.

Oso Grande Strawberry: Big and bold flavor

The Spanish name “Large Bear” fits the Oso Grande Strawberry perfectly. Scientists developed it in 1981 by crossing ‘Parker’ and Cal 77.3-603. This impressive variety has huge, firm berries with bright red color and an attractive finish. Penetrometer tests show the Oso Grande is remarkably firm – almost matching ‘Parker’ and much firmer than ‘Chandler’ or ‘Douglas’.

The Oso Grande’s standout feature is its taste: sweet notes balanced with just enough acidity. The plant does well in winter and summer plantings across coastal California. Harvests come later than ‘Chandler’ varieties. Its strong nature and long shelf life make it great for both commercial farms and home gardens.

Ogallala Strawberry: A sweet-tart American variety

The University of Nebraska and USDA created the Ogallala Strawberry in 1956. This special everbearing heirloom combines wild strawberries from the Rocky Mountains with domestic varieties. The result is a tough plant that grows well even in harsh conditions. The Ogallala can handle drought, produces lots of fruit, and survives extreme cold down to zone 3 temperatures.

These deep red berries taste like aromatic wild strawberries with a sweet-tart profile. They work great fresh, frozen, or in preserves. Most regions see fruit from June through September, while moderate climates get berries through most summer. The plants grow best in soil with pH levels between 5.3-6.5.

Oregon Grape: Tart and medicinal

Oregon grape (Mahonia aquifolium) isn’t actually related to grapes. These purplish-black berries grow in clusters on evergreen shrubs with holly-like leaves across western North America. The berries taste too tart and bitter to eat fresh but make excellent jams, jellies, sauces, and wine.

The plant has got attention for its healing properties. The root extract contains berberine – a powerful compound with antibacterial, anti-inflammatory, and bile-stimulating effects. New studies show it helps treat skin conditions like psoriasis and eczema. A 6-month clinical study found that 63% of people thought Oregon grape cream worked as well as or better than standard psoriasis medicines.

Otaheite Gooseberry: Sour but versatile

The Otaheite gooseberry (Phyllanthus acidus) isn’t related to regular gooseberries – they just share their sour taste. The fruit started in Madagascar before moving to Southeast Asia. These small, ribbed fruits turn pale yellow to white when ripe. They taste like “a supercharged lemon”, so people rarely eat them raw without preparation.

The Otaheite gooseberry shines in tropical cooking. Malaysian cuisine uses them in relishes, syrups, and sweet preserves. Filipino cooks make vinegar from them or eat them raw after soaking in salt. The berries provide good amounts of vitamin C (8mg per 100g) plus calcium, phosphorus, and iron. Indian traditional medicine uses them to boost blood and liver health.

Tropical and Exotic O-Fruits

The tropical climate holds a fascinating array of exotic fruits that start with O. Each fruit brings its own unique flavor and packs impressive nutritional benefits.

Otaheite Apple: A tropical delight from Southeast Asia

The Otaheite Apple (Syzygium malaccense) comes from Southeast Asia and the Pacific Islands. This beautiful crimson-red fruit looks like a pear but grows larger than regular apples. You’ll find its flesh crisp and sometimes spongy, with hints of rose water. Jamaica adopted this fruit in 1793, and it became their national treasure. People usually eat it raw, and its taste ranges from bland to tangy to sweet. Many locals turn it into sauces or jams by stewing it with brown sugar and ginger.

Osteen Mango: A Florida-grown favorite

S.A. Osteen planted a seed on his Merritt Island property in Florida back in 1935. The tree produced its first fruits in 1940, and they named it after the Osteen family. A ripe Osteen Mango weighs just over a pound and has an oblong shape with a rounded bottom. The smooth skin starts yellow but turns a deep purple as it ripens. The flesh stays almost fiber-free and offers a mild, sweet taste. This single-seeded variety has caught on in Europe while Florida farmers still grow it on a smaller scale.

Okra: A fruit often mistaken for a vegetable

Okra might look like a vegetable, but botanists actually group it with fruits. This green, finger-shaped pod traveled from Africa and brings a unique texture to dishes. A 100-gram serving contains just 33 calories but packs vitamins, potassium, calcium, fiber, and healthy fats. Cooks love okra’s flexibility – it works great in salads, stir-fries, roasted dishes, soups, and stews.

Oil Palm Fruit: Source of palm oil

Oil Palm Fruit grows in small clusters that range from reddish-orange to dark purple, mostly in West and Southeast Africa. These fruits give us palm oil, which made up about 36% of global oil crop production in 2014. Palm oil production shows impressive efficiency – it supplies 40% of the world’s vegetable oil using less than 6% of all vegetable oil farmland.

Opuntia: The prickly pear cactus fruit

The prickly pear cactus fruit, or “tuna,” shows off flesh in bright red, wine-red, green, or yellow-orange. Harvesting takes extra care because tiny hair-like splinters called glochids can stick in your skin. People usually burn off these glochids over an open flame before eating the sweet fruit raw or using it in jams, jellies, and drinks. This superfood comes loaded with antioxidants, vitamin C, and calcium. Research suggests it helps manage blood sugar and supports digestive health.

Stone Fruits and Melons That Start With O

Stone fruits and melons beginning with O represent nature’s most delectable orchard treasures. These fruits provide exceptional flavors and can be used in many culinary applications.

O’Henry Peach: Juicy and freestone

Large, firm O’Henry Peaches display full red skin and ripen by mid-August. This yellow freestone variety consistently ranks high in formal taste tests. The trees need 750 chill hours and thrive in USDA zones 5-9. These self-fruitful trees demonstrate strong, vigorous growth and produce heavy yields.

Opal Plum: Sweet and tangy European variety

Swedish horticulturists developed the Opal Plum in 1925. The fruit’s reddish-purple skin covers bright yellow flesh that separates easily from the pit. The plum’s excellent flavor draws comparisons to gage plums. These self-fertile fruits become the first European plums ready at the time July arrives.

Oullins Gage Plum: Golden and honey-like

Oullins Gage Plum’s pale gold skin surrounds sweet, tender greenish-yellow flesh. This French variety’s name comes from Oullins town near Lyon, also called “Reine Claude d’Oullins”. The fruit ripens by mid-August and experts praise its “exquisite flavor and handsome appearance”.

Ozark Premier Plum: Grown for sweetness

Missouri State Fruit Experiment Station introduced the Ozark Premier Plum in 1946. The variety produces extra-large fruits with red skin and yellow flesh. This heat-tolerant, semi-freestone plum needs cross-pollination to yield optimal results.

Ogen Melon: Fragrant and honey-flavored

Israel’s Ogen Melon shows distinctive stripes that change from dark green to golden yellow during ripening. The melon’s pale green flesh delivers honey-sweet flavors with a pleasant tang. A sweet, tropical aroma signals perfect ripeness.

Rare and Regional Fruits Worth Discovering

Rare and heritage fruits that start with O have specialized varieties that grow in specific regions. Each fruit has distinct characteristics that fruit enthusiasts love to explore.

Oeillade Noire Grape: A French wine grape

Southern France’s Languedoc and Provence regions traditionally grew Oeillade Noire, but this grape now faces extinction. The grape ripens mid-season and produces soft, fruity, light-bodied red wines with modest alcohol content that taste best when young. Wine producers can only make it as vin de table since AOC designated wines don’t permit its use.

Okuzgozu Grape: A Turkish red wine variety

This grape is Turkey’s most popular red variety, and its name means “bull’s eye” because of its large, fleshy berries. The grapes grow at elevations between 2,800 to 3,500 feet and create wines with plummy fruit notes, fine voluminous tannins, and a refreshing tang. Wine experts often compare its bright ruby color and raspberry, cherry, and mint aromas to Pinot Noir.

Orient Pear: Crisp and floral

Orient Pear trees yield large, bell-shaped golden yellow fruits with russeting and firm, sweet flesh. The trees need cross-pollination from Bartlett or Moonglow varieties to resist blight. These pears’ thick skin protects their creamy, fine-textured flesh, making them perfect to eat fresh, can, or bake.

Orin Apple: A Japanese apple with honey notes

Japan’s Aomori Apple Research Station created the Orin apple, which shows off russeted yellow-green skin and crisp, cream-colored flesh. This sweet and juicy apple tastes like honey mixed with hints of pineapple or pear. You can find Orin apples from October through January. They come from crossing Golden Delicious and Indo varieties.

Ozark Gold Apple: A sweet American cultivar

Missouri’s Mountain Grove Experiment Station developed the Ozark Gold apple that ripens three weeks before Golden Delicious. This dessert apple grows large to very large with bright-yellow waxy skin and sometimes shows a sunside blush. Its sweet flavor brings together honey, vanilla, and subtle pear notes.

Oval Kumquat: Sweet skin, tart inside

The Oval (Nagami) Kumquat creates an interesting contrast with its sweet, edible skin and sour pulp. People eat these small, elongated fruits whole, which creates a unique sweet-tart taste. California and Florida grow most of these fruits, which you can find from January through June in the U.S..
