Highlights

Hackberry might be the most underrated native tree in North America. It grows fast (2–3 feet per year), lives up to 200 years, laughs at terrible soil, and quietly supports an enormous web of wildlife. At least 29 bird species eat its tiny cherry-like fruit. Five butterfly species use it as a host plant, meaning their caterpillars literally cannot survive without it. And the fruit? It’s edible for people too, with a long history of human use going back thousands of years. (More on that in a moment.) Hackberry deserves a much better reputation than its name suggests.

Why hackberry matters

It’s a butterfly nursery tree

Hackberry is the host plant for five butterfly species. That means female butterflies lay their eggs on hackberry leaves, and the caterpillars feed on those leaves as they grow. No hackberry, no caterpillars. No caterpillars, no butterflies. Here are four butterflies that rely on this native tree to survive:

Mourning cloak butterfly, dark maroon wings edged in blue spots and cream

Beyond those four, the hackberry’s Celtis genus supports roughly 43 caterpillar species in the Mid-Atlantic region alone, including the Io moth and white-marked tussock moth. That makes hackberry one of the most important host plants for butterflies and moths east of the Rockies, right up there with oaks.

It’s a bird buffet

Hackberry fruit ripens in late summer and persists through winter, feeding birds exactly when they need it. Cedar waxwings, American robins, northern cardinals, gray catbirds, brown thrashers, hermit thrushes, northern mockingbirds, wild turkeys, and northern bobwhites all eat hackberry fruit. Even yellow-bellied sapsuckers (a crazy name for a woodpecker you wouldn’t expect to see eating fruit) go for hackberries.

Where is hackberry native?

Native to 39 US states, Washington, D.C., and 3 Canadian provinces (Manitoba, Ontario, Quebec)

Are hackberry fruit edible?

Yes! Hackberry fruit is edible for humans and has been a food source for thousands of years. The fruit is botanically a drupe (a botanical name for stone fruit), with a thin layer of flesh surrounding a hard-shelled pit. The pit itself contains a nutritious kernel that’s rich in calories, fat, protein, and calcium. Hackberries are tiny, so you can eat the whole thing! Crunch right through the pit to get to the kernel inside.

What do hackberries taste like?

Descriptions range from “like a date” to “like a tart cherry” to “not worth the trouble.” Sweetness varies dramatically from tree to tree. The best advice comes from native gardening expert Carolyn Harstad in her book Go Native: “You be the judge.”

Native Americans across the continent used hackberry fruit extensively. The Kiowa mashed berries into a paste, shaped it around sticks, and roasted them over fire. The Pawnee and Omaha mixed ground hackberry with fat and corn. Archaeologists have recovered hackberry seeds by the thousands from sites in Texas, some dating back centuries.

To quote the fantastic native expert Carolyn Harstad again: “Hackberry will accept nearly any growing condition.” So there you go—plant away!

Where hackberry shines in your yard

How to grow hackberry

Hackberries are one of the easiest native trees to plant. Some native trees have a reputation for being hard to grow (I’m talking about you, Franklin trees!) Hackberries are exactly the opposite: they are almost impossible to plant in the wrong spot.

Or, to quote the fantastic native gardener Carolyn Harstad again:

“Hackberry will accept nearly any growing condition.”

So there you go—plant away!

Where to plant

Full sun is best. Part sun works. Just avoid full shade. Beyond that, hackberry genuinely doesn’t care. Clay soil, sandy soil, rocky soil, rich loam are all fine. Moist ground, dry ground: both fine. The natural pH of hackberry habitat is around 7.1 (neutral), but it handles acidic and alkaline soils equally well. It even shrugs off urban conditions like compacted soil, heat, salt spray, and pollution.

When to plant

Fall or early spring, while the tree is dormant.

Spacing

Give hackberry room. Plan for 40–60 feet of spread at maturity. Space trees 30–50 feet apart if planting a group.

Watering

Water deeply once a week through the first growing season. After that, hackberry is remarkably self-sufficient. It handles drought well once established.

Mulching

A 2–3 inch layer of mulch around the base helps retain moisture during establishment. Keep mulch a few inches away from the trunk—no mulch volcanoes!

Pruning

Prune in late winter while dormant. In the first 10–20 years, focus on creating wide branch angles (around 120°) and removing any vertical branches that compete with the central leader. Hackberry can develop weak crotches if left unpruned, so a little early attention pays off.

Beginner tip

If you’re nervous about planting a tree, start with hackberry. It is genuinely hard to get wrong. Pick a sunny spot, dig the hole, water it through the first summer and dry spells, and walk away. Hackberry will take it from there.

What are good pairings for hackberry trees?

Hackberry’s adaptability means it pairs well with a huge range of native plants. These companions look great alongside it and share similar easy-going growing needs:

Where can I buy a hackberry tree to plant?

Now that you want a hackberry, let’s set you up for success in finding one. Sadly, most conventional nurseries do not stock this native tree (I know…it’s so silly how many non-native plants are better known).

To make finding a hackberry easier, here are four sourcing ideas:

Cultivars to consider (and related species)

There aren’t a ton of hackberry cultivars, but the ones that exist solve specific problems:

FAQs

Why is it called hackberry?

Wow. “Hackberry.” You have to wonder how popular this tree would be if it were called ‘Birdsong Tree’ or ‘Butterfly Nursery Tree.’

“Hackberry” comes from the old Scottish word “Hagberry,” which means “bird cherry.” Which is exactly what this tree should be called. Bird cherry is the perfect name for this beautiful tree, thanks to its tiny cherries, which are bird favorites.

Fortunately, common names are given by the generations before, so we can all find a way to change hackberry to something that does this incredible tree more justice—Bird cherry gets our vote. To ensure you’re getting the right tree, look for the Latin name Celtis occidentalis (each species of plants only have ONE Latin name, which is why they were created in the first place.)

Do hackberry trees get messy?

The fruit can drop onto sidewalks and patios, and the tiny psyllids can be a minor nuisance in fall. If you plant hackberry over a patio, you’ll notice. But the birds usually eat the fruit before it becomes a real problem, and the psyllids disappear after the first hard freeze.

How big do hackberries get?

Big. Expect 40–60 feet tall and wide in most landscapes, with some trees reaching 75–100 feet in ideal conditions. Plan for it. If you want the same wildlife value in a smaller package, look at dwarf hackberry (Celtis tenuifolia) instead.

Plant nerd fact

What is this cluster twig thing in my hackberry?

Spot a firework of tiny branches in your hackberry? That is what’s called a witches’ broom.

Hackberries and witches’ brooms come from one of the strangest ecological relationships in the tree world. A tiny eriophyid mite (Eriophyes celtis) and a powdery mildew fungus (Sphaerotheca phytoptophila) team up to hijack the tree’s growth, creating dense, bushy clusters of dwarfed twigs. It does indeed look like it’s made for tiny, fairy-sized witches:

A single large hackberry can carry these brooms without breaking a sweat. The mite-fungus partnership triggers the tree to grow the brooms, and the mite lives inside them. Scientists have studied this for over a century and still aren’t entirely sure why the tree doesn’t simply fight it off. The going theory: hackberry grows so fast and so vigorously that the brooms are barely a nuisance, like a bodybuilder ignoring a mosquito bite.

Hackberry is one of the most generous trees in North America. It grows fast, asks for almost nothing, feeds birds and butterflies for decades, and even offers fruit you can eat yourself. It thrives in soil that would defeat most trees, laughs at drought, and shrugs off urban conditions. The only thing holding it back is a lousy name. Don’t let that stop you. Plant a hackberry and give your yard a butterfly nursery, a bird buffet, and a shade tree that’ll outlast you. We’ve included hackberry in our Best Native Trees for Front Yards and Best Native Plants for Birds round-ups for good reason. If you’re new to native plants, our What is a native plant? page is a great place to start. Happy planting!
