Edible Landscape Design: Hazelnut (Filbert) — Top 10 Permaculture Species

The Shrub That Feeds You, Hides You, and Outlasts the Grocery Store

Continuing the series on species that earn their keep in a resilient permaculture designed landscape, let me introduce you to the mighty hazelnut. Why the hype?

Because in permaculture, plants have to work overtime. They can’t just look pretty in the corner. They need to feed you, fuel you, shelter you, and not die the first time you forget to water them. Hazelnut checks those boxes and then some. It’s a staple food. It’s a calorie source that comes with its own built-in container. It’s oil in a shell. It’s fencing on demand. It’s habitat and hedge. And it doesn’t whine about drought or soil like your tomatoes do.

Self Storing Calories

Here’s the thing about hazelnuts: they aren’t just “snack food.” They’re real food. Dense with oil and protein, they deliver the calories that actually keep you upright in February when the kale patch froze out three months ago.

Eat them raw, roast them, grind them into flour, or press them for oil. Hazelnut flour is gluten-free, flavorful, and fills out bread or pastry like it was born to. Hazelnut oil rivals olive oil in stability and richness, and unlike your neighbor’s backyard olives, you can actually grow this stuff here. Even the leftover press cake has a purpose: high-protein feed for livestock. Nothing wasted.

Storage? Forget bruised apples and pears that turn to compost before you can finish a bucket. Hazelnuts, in shell, will hold for up to two years with nothing more than a cool, dry place. Shelled, they’ll go six to twelve months, longer if you freeze or vacuum seal. You’re not just harvesting, you’re banking calories.

Hazelnut Pollination: Getting Them to Fruit

One hazelnut by itself is like a hermit at a barn dance—it won’t do much. Hazels are monoecious (male and female flowers on the same plant), but they’re self-incompatible. Translation: they need a partner.

The fix is simple: plant at least two different varieties. If space is tight, you can even graft a different variety onto the same shrub and turn one plant into its own pollination team.

Built for Low Maintenance

Some plants come with drama. Prune them wrong and they sulk. Skip a spray and they collapse. Hazelnuts don’t play that game. They thrive on a little rough treatment. Coppice them every few years and they answer back with fresh poles—ready for fencing, trellises, tool handles, or firewood.

And the leaves? Don’t rake them into yard waste. They break down into an excellent mulch—nutrient-rich, quick to decompose, and perfect for feeding the soil around fruit trees or vegetables.

Modern disease-resistant cultivars—Jefferson, Yamhill, Eta, and Gamma—make hazelnuts even more resilient. Where chestnuts still carry the burden of blight, hazels largely shrug off their own scourge, Eastern Filbert Blight, when you choose the right varieties.

Ecological Workhorse

Hazelnuts don’t just feed people—they build landscapes. Plant them in rows and they’ll form hedges, windbreaks, or a privacy screen so thick you’ll forget you had neighbors. Left as multi-stemmed shrubs, they make a screen that doubles as food security: dense, resilient, and productive.

But let’s be honest: the screen disappears in winter when the leaves drop. And while you’re imagining baskets of nuts, so are the squirrels. They will strip a planting faster than you can say “filbert.” Plan accordingly.

Meanwhile, wildlife cashes in. Birds nest, pollinators linger. The roots hold slopes together like rebar in a house foundation. And when you’ve taken the nut, the so-called waste turns out to be a resource: shells that burn hot and clean, mulch that outlasts leaves, biochar to lock carbon back in the ground. Even industry has found a use for them—as abrasives for polishing and blasting.

A Simple Hazelnut Recipe

Want proof hazelnuts belong in the pantry and your stomach?

Try this:

Roasted Hazelnuts with Sea Salt & Honey

1. Preheat oven to 350°F (175°C).

2. Spread shelled hazelnuts in a single layer, roast 12–15 minutes until skins split.

3. Rub warm nuts in a towel to shed most skins.

4. Toss with a drizzle of honey and a pinch of sea salt while still hot.

You’ll never look at trail mix the same way again.

Why It Belongs in Your Permaculture Design

The filbert has been feeding humans for thousands of years, from Anatolia to Oregon. It bridges the domestic and the ecological: calories, oil, fuel, fencing, screens, wildlife, soil cover. It gives more than it takes.

If you’re serious about edible landscape design, hazelnut isn’t a side note. It’s a backbone species. Plant it, and you’re not just landscaping—you’re building resilience that can stand on its own.
