Autumn olive (Elaeagnus umbellata) is a tasty edible wild fruit that ripens late in the fall. The plants are nitrogen fixers, which means they can grow on incredibly poor soil. Combine that with exceptional cold hardiness, and they’re the perfect fruit to forage where little else will grow.
Learn how to identify autumn olive, distinguish it from Russian olive and other look-alikes, and use the lycopene-rich red speckled berries in jam, ketchup, fruit leather, and more.

Autumn olive is one of the most prolific wild fruits you’ll find, and it’s a favorite for foragers willing to embrace this abundant plant. Though often labeled invasive, it produces an incredible bounty of tart-sweet berries each fall, perfect for jams, sauces, and snacking right off the bush.
I first stumbled onto a massive thicket of autumn olive while hunting for wild grapes, and the sheer volume of fruit was staggering. Once you know what to look for, you’ll see autumn olive everywhere, and you’ll never leave empty-handed. A single mature shrub can produce up to 80 pounds of fruit in a good year, which is part of why this plant has become such a favorite among foragers willing to work with an abundant harvest.
Notes from My Homestead
Autumn olive isn’t terribly common in our corner of Vermont (we’re at the northern edge of its naturalized range), but I’ve found a few productive stands along old railroad cuts and abandoned pasture lines south of us. The first time I really paid attention to autumn olive was on a fall foraging trip into southern Vermont, where it grows in dense thickets along forest edges and produces such a quantity of fruit that you can fill a five-gallon bucket in 30 minutes if you find a good shrub at peak ripeness. The silvery undersides of the leaves catch the wind and give the whole plant a shimmery appearance, which is honestly one of the easier wild fruit shrubs to spot at a distance once you’ve trained your eye.
For our family, autumn olive berries mostly become fruit leather and the occasional batch of autumn olive jam. The kids love the bright pomegranate-tomato flavor, and a tray of fruit leather strips made from milled autumn olive pulp keeps in the pantry for weeks (when it’s not getting raided for snacks).
What Is Autumn Olive?
Autumn olive (Elaeagnus umbellata) is a deciduous shrub or small tree originally from Asia, introduced to North America for erosion control and wildlife habitat. It has since naturalized widely and is considered invasive in many areas, particularly in the eastern and central United States.
The plant was deliberately introduced to the US in the 1830s and was promoted heavily by the US Soil Conservation Service in the 1950s as a windbreak shrub, an erosion-control plant for strip-mined land, and a wildlife food source. It performed too well: birds spread the seeds widely, and autumn olive is now considered a major invasive across most of its introduced range. From a foraging standpoint, this is a happy problem; harvesting autumn olive is one of the few wild-food activities where you can take as much as you want without any concern for over-harvesting the species.
Autumn olive grows quickly in poor soils, disturbed areas, fields, and along roadsides. It’s a hardy perennial that thrives in full sun and poor conditions where few other plants can survive. The plant is also a nitrogen fixer (one of very few non-legume species with this ability), which is part of why it’s such an aggressive colonizer of disturbed land.
Other common names include autumnberry, Japanese silverberry, and oleaster. Some foragers prefer “autumnberry” or “silverberry” because “autumn olive” suggests a relationship to true olives that doesn’t really exist; the fruit is bright red, tart-sweet, and nothing like a martini olive in flavor or use.
Is Autumn Olive Edible?
Yes, autumn olive berries are edible, and quite nutritious. The ripe berries are tart and sweet, with a unique flavor often described as a cross between pomegranate and tomato. They are best eaten fresh, cooked into jams and sauces, or dried.
Autumn olive berries are particularly high in lycopene, an antioxidant compound also found in tomatoes. Studies have measured lycopene levels in autumn olive berries at up to 17 times higher than in tomatoes, making them one of the richest natural sources known. However, the seeds inside are best swallowed whole or spit out, as they can be slightly astringent if chewed.
Their high lycopene content (like tomatoes) inspired quite a few autumn olive ketchup recipes among forager friends, and they’re all delicious. It works out particularly well since you pass the autumn olives through a food mill to remove the seeds.
Unripe autumn olive berries are intensely astringent and can cause stomach upset for some people. Wait until the berries are fully ripe (deep red with silvery speckles, slightly soft to the touch) before harvesting any quantity for fresh eating. Cooking, drying, or freezing all reduce the astringency further, so unripe or partially ripe berries can still be useful in cooked preparations.
The autumn olive flowers are also edible and are sometimes used in herbal preparations, salads, or garnishes. The flowers have a strong, sweet, lily-like fragrance and a mild, slightly nutty flavor.
Autumn Olive Medicinal Benefits
Autumn olive berries are renowned for their extremely high lycopene content, often higher than tomatoes. Lycopene is associated with antioxidant benefits, including supporting heart health and potentially reducing cancer risk. The berries are also a good source of vitamins A, C, and E, plus flavonoids and phenolic compounds that contribute to documented antioxidant activity.
In traditional practices, autumn olive has also been used for general immune support and as a mild astringent.
That said, this is one of the few wild edible plants with very little documented medical research. While wild black cherry is great for coughs, and teaberry is great for nerve pain, autumn olive’s medicinal actions remain a mystery as it hasn’t been studied nearly as much as other wild edible fruits and berries.
Where to Find Autumn Olive
Autumn olive is widespread across the eastern and central United States and into southeastern Canada (especially southern Ontario), thriving in sunny, disturbed areas like abandoned fields, pastures, roadsides, and open woodlands. It tolerates poor, sandy, or rocky soils and can quickly colonize areas where other plants struggle. Missouri, Pennsylvania, Ohio, Indiana, and the broader Appalachian region are particularly heavy autumn-olive country.
You’re likely to find it forming dense thickets wherever the ground has been cleared or disturbed. Some of the most productive stands grow on:
- Old strip-mining sites in Appalachia (where it was deliberately planted for revegetation)
- Highway medians, embankments, and along rural roads
- Old railroad cuts and abandoned rail corridors
- Abandoned fields, pastures, and farm edges
- The sunny edges of mixed hardwood forests
- Suburban hedgerows and old shelter belts
Avoid harvesting from busy roadsides, since autumn olive picks up petroleum residue and heavy metals from contaminated soils. The cleanest harvests come from rural roadsides, organic farm edges, and old pasture lines well away from sprayed crops. Also avoid areas where invasive-species control programs may have used herbicide, which is increasingly common where autumn olive is being actively managed.
When to Find Autumn Olive
Autumn olive flowers in late spring, producing small, fragrant, creamy-yellow blooms. The fruit develops through summer and ripens in early to mid-fall, usually from September through November depending on location. Look for ripe berries when the leaves begin to yellow in autumn.
The berries are at their sweetest after a light frost, which breaks down some of the astringency and concentrates the sugars. In good locations, autumn olive berries persist on the shrubs well into December, so the harvest window is generously long. Many foragers do their first harvest in late September for fruit leather and jam, then circle back in November for a second harvest of sweeter berries for fresh eating.
Autumn olive can also be identified in winter when the leaves have fallen, by the silvery young twigs, the spreading shrub habit, and (sometimes) the persistent dried berries hanging on the branches. Winter identification is useful for scouting locations to harvest the following fall.
How to Identify Autumn Olive
Autumn olive is a spreading shrub that typically grows 6 to 20 feet tall. It has a bushy growth habit with multiple stems arising from the base. The key to identifying autumn olive lies in its silvery foliage and abundant clusters of small red berries.
As is typical with an invasive species, autumn olive trees grow quickly. The shrub begins producing fruit when it’s three years old and has an average fruit-producing lifespan of 40 years.
Autumn Olive Leaves
Depending on where you live, autumn olive leaves first begin to appear in March and throughout early May, with each leaf growing from 2 to 4 inches in length.
The leaves are an elongated oval, or elliptical, shape and grow alternately (this means that one leaf grows from each plant node on alternate sides of the branch). The edges of the autumn olive leaf are classified as being undulate, or wavy, and have an entire margin, meaning the leaf has no teeth or serration marks.
The tops of the leaves are green, while the undersides are distinctly silvery and covered in tiny scales, giving them a shimmery appearance. This silvery underside is the single most reliable identification feature for the genus Elaeagnus; if you flip a leaf and the underside is not silvery, the plant is not an autumn olive.
As you can see in the pictures below, the topside of the leaf is a true green, while the underside is more of a slate green flecked with small golden-brown spots.
You’ll also notice the underside of the leaf has a rougher, scaly texture while the topside is comparatively smooth.
While the leaves are relatively nondescript from a distance, looking at the undersides will really help you identify Elaeagnus species.
Autumn Olive Bark
The twigs on a young autumn olive tree are a lighter shade of brown with a silvery patina, you’ll also see small tawny-colored scales speckling the branches. The thorns on young branches are typically quite long, so take care when you’re scouting out possible foraging locations!
As the tree ages and grows, the color of the bark turns to a light gray or grayish-brown color. You’ll notice that the bark on mature autumn olive trees is more fibrous and that it peels off in long, narrow strips.
Young stems are often brown or olive-green and speckled with silver or brown scales. Older stems become gray and woody.
Some plants produce small thorns, but many do not. The thorns, when present, are usually 1 to 2 inches long and sharp enough to require attention when you’re harvesting. Older shrubs sometimes lose their thorns entirely as the lower branches mature.
Autumn Olive Flowers
The flowers are small, tubular, creamy-yellow, and highly fragrant. They bloom in clusters in late spring and are an important nectar source for pollinators.
The blooms from the autumn olive tree have a strong floral scent. The aroma is often compared to lilies or sometimes to a sweet, slightly cloying gardenia. You’re most likely to smell them from April through June, when they’re in full bloom. The scent carries on the wind for surprising distances; a stand in full bloom can perfume an entire field edge, and many foragers locate productive stands in May by following their nose.
The tubular flowers are light yellow or cream-colored with bright yellow stamens; each flower has four petals. The blooms typically grow in clusters of 1 to 10 flowers.
I’ve actually found these plants by their scent in spring, literally following my nose to a patch.
Autumn Olive Fruit
The berries are small (about ¼ inch across), round to slightly oval, and bright red when ripe, often with silver speckles on the surface. They grow in dense clusters and are easily stripped from the branches by hand.
Unripe autumn olive fruits, or autumn berries, are small and silvery green.
Once the fruit has fully matured, in September and October, the berries turn a bright speckled red or pink. Each berry contains a single elongated seed (technically a stone, since autumn olive fruits are drupes), and the silvery surface speckles are a useful identification feature that distinguishes autumn olive from many other red-fruited shrubs.
They’re best after a light frost in late autumn, but I think they’re great eating as soon as the leaves start to yellow even if there hasn’t been a frost yet.
Autumn Olive Look-Alikes
Autumn olives are fairly easy to identify but there are a few look-alikes to be aware of. When in doubt, remember that autumn olive trees will always have alternate leaves and small scales covering the bark, the underside of the leaf, and the fruit.
The most important distinction to learn is between autumn olive and Russian olive (the two are widely confused, both invasive, and they sometimes grow together). The other Elaeagnus family members are themselves edible, so confusion is not a safety issue. The honeysuckles are the look-alikes to watch closely; some are mildly toxic and the leaves and growth habits are reasonably similar.
Autumn Olive vs. Russian Olive
Russian Olive (Elaeagnus angustifolia) is the closest look-alike to autumn olive, and the two are widely confused. Both are invasive Asian shrubs in the same genus, both have silvery foliage, and both are sometimes deliberately planted as windbreaks. The differences:
- Russian olive has narrower, more lance-shaped leaves (autumn olive has broader, oval leaves).
- Russian olive leaves are silvery on both sides (autumn olive leaves are green on top and silvery only underneath).
- Russian olive produces dry, mealy, yellowish or yellow-orange fruits about ½ inch long (autumn olive produces juicy red speckled berries about ¼ inch across).
- Russian olive fruits are technically edible but not really worth eating; they’re mealy and bland and considered famine food rather than a forager’s prize.
- Russian olive grows more often into a small tree shape (15 to 30 feet); autumn olive stays more shrub-like (6 to 20 feet).
- Russian olive is more cold-hardy and is the more common Elaeagnus in the western US and northern plains; autumn olive dominates the eastern half of the country.
If you’re looking at silvery foliage and wondering which one you’ve got, check the fruit color and shape: red speckled and round means autumn olive, yellowish and oblong means Russian olive.
Silverberry
Silverberry (Elaeagnus commutata) is a North American native species in the same genus, found mainly in the northern Rockies, prairies, and Canadian boreal forest. The differences:
- Silverberry fruits are silvery or grayish (not red) when ripe.
- Silverberry tends to grow as smaller, more compact shrubs (3 to 10 feet) compared to autumn olive’s 6 to 20 feet.
- Silverberry is native and not invasive, so harvesting should be moderate.
Silverberry fruits are technically edible, though they’re dry and mealy similar to Russian olive and not generally considered a top forager’s choice.
Buffaloberry
Buffaloberry (Shepherdia argentea) is a different genus but shares the silvery foliage characteristic. It’s native to western North America. The differences:
- Buffaloberry has opposite leaves (autumn olive has alternate leaves) — this is the easiest single ID feature.
- Buffaloberry shrubs are typically thornier than autumn olive.
- Buffaloberry leaves are grayish-silver on both sides.
Buffaloberries have similar bright red fruits and are themselves edible (though tart and saponin-rich; traditional Indigenous use whips them into a foamy “Indian ice cream” preparation).
Invasive Honeysuckles
The most important non-Elaeagnus look-alike to know is the invasive Asian honeysuckles, particularly Amur Honeysuckle (Lonicera maackii) and Japanese Honeysuckle (Lonicera japonica). The honeysuckle berries are mildly toxic and shouldn’t be eaten. Key distinguishing features:
- Honeysuckles have opposite leaves (autumn olive has alternate leaves).
- Honeysuckle leaves are uniformly green on both sides (no silvery underside).
- Honeysuckle berries grow in pairs along the stem rather than in dense autumn-olive-style clusters.
- Honeysuckle stems are hollow when mature; autumn olive stems are solid wood.
- Japanese honeysuckle is a climbing vine; autumn olive is a free-standing shrub.
The single best test is to flip a leaf: silvery underside means autumn olive (or another Elaeagnus), uniformly green means honeysuckle. The honeysuckle leaves and growth habit can be deceptively similar at a glance, but the leaf underside difference is unmistakable.
How to Harvest Autumn Olive
Autumn olive fruit is at its sweetest when it’s been allowed to fully ripen on the stem. While your mileage may vary depending on where you live, I can typically harvest these berries all the way through December. The longer you can wait, especially if you can hold off until after the first frost, the tastier autumn olive berries will become.
A word of warning: Unripe autumn olive berries have an intensely astringent flavor and can cause stomach upset for some people.
These berries can be somewhat tedious to pick one-by-one, so I recommend gently shaking them directly from the branch into a bucket, removing any small twigs or broken leaves from the berry pile as you work.
An even faster method is to lay a tarp under the shrub and gently shake the larger branches; ripe berries fall and land on the tarp, while underripe berries cling to the branch. This is a smart way to avoid the thorns on younger branches and ensure you only take fully ripe fruit. A productive shrub can yield several gallons of berries in 20 minutes with the tarp method.
If you plan on processing the berries for jam (or any other recipe that involves a sieve or straining step), you don’t have to be as careful picking out extraneous bits of autumn olive detritus.
Fresh autumn olive berries don’t keep especially well; they should be processed within a few days of harvest, or frozen for later use. Frozen whole, they keep well for up to a year and can go straight from the freezer into jam, jelly, or fruit leather without thawing.
Recipes Using Autumn Olives
Autumn olive berries have a deep, jammy flavor, making them ideal for dessert recipes and homemade condiments. My kids love it when we make autumn berry fruit leather, it’s an activity the whole family can do together.

Autumn Olive FAQs
Yes, autumn olive berries (Elaeagnus umbellata) are fully edible and quite nutritious. The ripe berries are tart-sweet with a flavor often compared to a cross between pomegranate and tomato. They contain extremely high lycopene levels (up to 17 times higher than tomatoes) and are a good source of vitamins A, C, and E. The berries can be eaten fresh once fully ripe, or cooked into jam, ketchup, fruit leather, and syrup. Unripe berries are intensely astringent and can cause mild stomach upset.
Autumn olive (Elaeagnus umbellata) and Russian olive (Elaeagnus angustifolia) are closely related invasive Asian shrubs often confused with each other. The main differences: autumn olive has broader oval leaves with a distinctly silvery underside (Russian olive has narrower lance-shaped leaves that are silvery on both sides); autumn olive produces juicy red speckled berries about a quarter inch across (Russian olive produces dry mealy yellowish-orange fruits about half an inch long); autumn olive stays more shrub-like, while Russian olive often grows into a small tree. Both are technically edible, but autumn olive berries are far more flavorful and useful as a foraged fruit.
Autumn olive berries ripen from late September through November depending on location, with the best harvests typically in October. The berries change from silvery-green to bright red with silver speckles as they ripen, and they’re at their sweetest after the first light frost, which breaks down some of the astringency. The berries persist on the shrubs into December in many areas, so the harvest window is generously long. Wait until the berries are fully red, slightly soft, and easily detach from the branch with gentle pressure.
No, autumn olive berries are not poisonous. They’re fully edible and have been safely eaten for centuries in Asia (where the species is native) and increasingly in North America (where it’s naturalized as an invasive species). The seeds inside are technically edible too but are slightly astringent if chewed and are usually swallowed whole or strained out. Unripe autumn olive berries can cause mild stomach upset due to high tannin content, so wait until they’re fully ripe (deep red with silver speckles, slightly soft to the touch) before eating any quantity.
Autumn olive berries have a distinctive tart-sweet flavor often described as a cross between pomegranate, tomato, and cranberry. The taste varies considerably between individual shrubs and based on how ripe the berries are: less ripe berries are intensely astringent and tannic; fully ripe berries are sweet-tart with a hint of fruitiness; post-frost berries are at peak sweetness. The flavor pairs particularly well with cinnamon, citrus, and warming spices, which is why autumn olive jam, ketchup, and shrub (drinking vinegar) recipes are some of the most popular ways to use the harvest.

If there are no autumn olive trees near where I live, are dried silverberries a good alternative in terms of lycopene content?
I believe so, but I’m not 100% sure.
Have you tried making wine with these berries?
I haven’t personally tried this but I have seen others who have. If you decide to try it, be sure to let us know how it goes.
Ashley – I love following your page and newsletter. Do you have a book out yet where i can find all this great info for my off-grid library?
Sorry Dee, there is no book at this time. Lots of people have asked so maybe one day.
I love this post! I have been foraging autumn olives for years, and always make what I call my “Christmas” jam. I have found that cinnamon complements Autumn Olives, Some cinnamon added to the jam makes the flavor reminiscent of autumn and winter. A taste of the holidays all year ’round! I would give my specific recipe, but it varies depending on the size of the harvest and the types of berries I mix in and their various natural pectin levels. I am going to try the lemon and autumn olive tart listed in the article.
As for harvesting, I just dip branch into a bag and slide those berries in. I have found trees so abundant that i have collected a gallon of berries in 5 minutes or less. Of course in suburbia, I make sure that anything I forage is away from roads.
That’s wonderful and your jam sounds amazing. So glad you enjoyed the post.
My favorite use of the autumn olive berries is in my Autumn-Raz Jam. I use a ratio of 2-1 or 3-1 (autumn olive to raspberries, frozen or fresh), and prefer Pomona’s Pectin, allowing a soft gel set with less sugar. The color of the jam is intensely scarlet, and the flavor is equally potent, in the very best way! Great on toast, or as the base layer of a shortbread fruit tart.
That jam sounds amazing!
Great information! Wish there were better pictures.. sorry but thanks!
Wow that’s great information to know since I have bookoos of these on my little farm! 😃 I had tasted a couple of the berries before but I didn’t know they were actually harvested by anyone other than the birds and deer! Haha
