Is Hazelnut a Tree or Shrub? Pollination & Family Explained
Welcome, young nature explorers! Do you enjoy eating crunchy, tasty nuts in chocolate or as a snack? Then you might know the Hazelnut! Today with Vedantu, we’ll uncover amazing details about the Hazelnut Plant — from its scientific name to its nutty secrets, uses, and some cool exam practice, too. Let’s dive into the wonderful world of hazelnuts!
Say Hello to the Hazelnut Plant!
What’s in a Name?
The Hazelnut Plant is also fondly called the Filbert. Its main scientific name is Corylus avellana when it grows in Europe, and Corylus americana in North America. The hazelnut belongs to the Betulaceae family. This family also includes birch trees. Hazelnut plants grow wild in temperate regions where summers are warm and winters can be cold.
Is It a Bush or a Tree?
This question confuses many students! The hazelnut plant is usually a shrub with many stems, but with the right care, it can also look like a small tree. It grows about 3–6 meters tall and likes to spread out. Because of its shape, it’s called both a ‘hazelnut bush’ and a ‘hazelnut tree’ — and both are correct!
Where Does the Hazelnut Live?
You can find Hazelnut plants in the wild forests and gardens of Europe, North America, and even parts of Asia. American hazelnuts enjoy cooler climates, while others prefer a typical temperate region.
All About Hazelnut Plant Parts!
Spot the Leaves, Flowers, and Nuts
- Leaves: The leaves are simple (one piece), round or oval, and have doubly saw-toothed (serrated) edges. They grow one after another along the stem (alternate).
- Flowers: Hazelnuts are monoecious, which means they have male and female flowers on the same plant. The male flowers hang down in soft, fuzzy clusters called catkins and produce yellowish pollen. The female flowers are tiny and mostly hidden, but you might spot bright red tips poking out.
- Fruit (Nut): Hazelnut nuts grow inside a tough shell, which is protected by a leafy cover called an involucre. When ripe, these shells fall to the ground, ready for people and animals to eat!
How Does It Grow?
Hazelnut plants start producing nuts just 3 to 4 years after planting. They can live and give fruit for over 40 years! Most are planted in pairs or groups because they use the wind to carry pollen between different plants for best nut production. Want to learn more about how plants pollinate?

Why Is the Hazelnut So Special?
Tasty Treats and Helpful Uses
- Yummy Food: Hazelnuts are tasty raw, roasted, or mixed into desserts. They are the star in snacks like chocolates and spreads.
- Healthy Nut: Hazelnuts are full of good fats, Vitamin E, and protein. Some people use hazelnut oil for cooking or even on skin!
- Good for Wildlife: Birds and animals love to eat fallen hazelnuts, and the bush gives protection to small creatures.
- Soil Helpers: Their thick roots help keep the soil from washing away.
Culture and Economy
Did you know? Hazelnuts are famous in chocolate spreads like Nutella! Large farms in Turkey, Italy, and the USA grow them for food companies. In some countries, hazelnut bushes are planted for their pretty yellow leaves in autumn.
Hazelnut or Walnut – Can You Tell the Difference?
Many nuts look alike, but the hazelnut and walnut are not close family! Here’s how you can spot the difference:
| Feature | Hazelnut | Walnut |
|---|---|---|
| Genus | Corylus | Juglans |
| Fruit Type | Nut (with leafy husk) | Drupe (with thick shell) |
| Plant Family | Betulaceae | Juglandaceae |
| Use in Food | Raw, roasted, desserts | Snacks, oil, baking |
Hazelnut Quick Facts Table
| Feature | What It Means | Fun to Know |
|---|---|---|
| Common Name | Hazelnut, Filbert | Also called Cobnut in some places! |
| Scientific Name | Corylus avellana (Europe), Corylus americana (America) | Betulaceae family buddies with birch! |
| Plant Type | Deciduous shrub or small tree | Can live 50+ years with care |
| Edible Part | Nut (seed inside hard shell) | The nut is inside a leafy husk |
| Native Range | Europe, Asia, North America | Loves temperate weather |

Fun Q&A Example
Q: Is the hazelnut plant a tree or a bush?
A: It’s mostly a bush (shrub) with many stems, but it can grow as a small tree.
Q: Do you need two hazelnut plants to get nuts?
A: Yes! Hazelnuts need cross-pollination, so two different plants help them produce lots of nuts.
Q: Which part of the hazelnut plant do we eat?
A: The nut — it’s really the seed inside a tough shell!

Common Hazelnut Mix-Ups Solved
- Hazelnut is both a bush and a small tree — it depends on how it grows and is pruned.
- Hazelnut is not related to walnut! Their families and fruits are different.
- Hazelnut flowers need wind and cross-pollination, so you get more nuts if you plant two different varieties together.
Let’s Wrap Up with Some Crunchy Facts!
Hooray! Now you know that the hazelnut plant is a friendly shrub or small tree from the Betulaceae family, famous for its tasty edible nuts and pretty autumn leaves. It helps both people and animals, and is a common exam topic for NEET, CBSE, and ICSE. With this Vedantu guide, you’ll never mix up your nuts or their plant families again!

FAQs on Hazelnut Plant: Key Concepts, Morphology & Exam Guide
1. Is hazelnut a tree or bush?
Hazelnut plants are primarily classified as large deciduous shrubs, though they can also grow as small trees under favorable conditions.
- Typically, hazelnuts are multi-stemmed and pruned into a bush form.
- Certain varieties may develop a single trunk and resemble a small tree.
- Hazelnut belongs to the Betulaceae family and key species include Corylus avellana (European hazelnut).
2. Do you need two hazelnut trees to get nuts?
Yes, cross-pollination between two genetically distinct hazelnut plants is usually necessary for abundant nut production.
- Hazelnut plants are mostly self-incompatible and require pollen from a different variety.
- Planting at least two different compatible cultivars increases fruit set.
- This aids with effective pollination and maximizes yield for both home gardens and commercial orchards.
3. What family does the hazelnut plant belong to?
The hazelnut plant belongs to the Betulaceae family.
- Its botanical name is typically Corylus avellana (European hazelnut).
- Another common species is Corylus americana (American hazelnut).
- This family also includes birches and alders.
4. What are the main uses of the hazelnut plant?
Hazelnut plants have multiple uses, both edible and ecological.
- Edible nuts: Consumed raw, roasted, or ground in sweets and spreads (e.g., chocolate and praline).
- Medicinal uses: Hazelnuts are rich in Vitamin E and antioxidants; oil is used in cosmetics.
- Wildlife and ecological value: Leaves, nuts, and shelter for birds and animals; prevents soil erosion.
5. How do you distinguish hazelnut from walnut?
Hazelnuts and walnuts differ in genus, fruit type, and appearance.
- Hazelnut: Genus is Corylus; produces a true nut enclosed in a leafy involucre; family Betulaceae.
- Walnut: Genus Juglans; fruit is a drupe with a hard, grooved shell; family Juglandaceae.
- The shell shape, tree structure, and taste also differ between the two.
6. Are hazelnuts hard to grow?
Hazelnuts are moderately easy to grow in suitable climates with proper care and site selection.
- They prefer well-drained soil and temperate climates with a winter chilling period.
- Some varieties like Corylus americana are more disease-resistant.
- Regular pruning and cross-pollination are needed for healthy yields.
7. Can you eat hazelnuts straight from the tree?
Hazelnuts can be eaten straight from the tree after maturity, but are often better after drying or curing for improved flavor.
- Fresh nuts may taste less sweet; curing enhances sweetness and storage life.
- Ensure nuts are fully ripe and free from mold or pests before direct consumption.
8. What are the pollination requirements for hazelnut plants?
Hazelnut plants require cross-pollination for good nut set, as most are self-incompatible.
- Both male (catkins) and female flowers are present on the same plant (monoecious).
- Wind pollination spreads pollen between compatible cultivars.
- Planting two or more varieties is recommended for gardens and orchards.
9. What are the main botanical features of the hazelnut plant?
Hazelnut plants have distinct morphological features important for exam diagrams.
- Leaves: Simple, rounded or oval, with double serrate margins and alternate phyllotaxy.
- Flowers: Monoecious—male catkins and small, bud-like female flowers.
- Fruit: Edible nut enclosed in a hard shell and a leafy involucre (husk).
10. What is the scientific name for the European and American hazelnut?
The scientific name for European hazelnut is Corylus avellana; for American hazelnut, it is Corylus americana.
- Both belong to the Betulaceae family.
- These names are frequently required in exams for plant identification and classification.
