## Appearance

The common hazel is a multi-stemmed shrub or small tree with broad, rounded, doubly-toothed, hairy leaves. It displays long, yellow-green male catkins in early spring, later producing distinctive edible nuts nestled in leafy green husks.

## Taxonomy

- **Kingdom:** Plantae
- **Phylum:** Tracheophyta
- **Class:** Magnoliopsida
- **Order:** Fagales
- **Family:** Betulaceae
- **Genus:** Corylus

## Interesting facts

- A single common hazel bush can produce thousands of delicious, energy-packed hazelnuts each autumn.
- Ancient humans have been eating hazelnuts for over 9,000 years, making them one of our oldest foods!
- Hazelnuts are so buoyant they can float in water, helping them travel to new places if dropped near streams.
- Its strong yet flexible wood was once used to weave wattle fencing and even make magic dowsing rods!

## Special abilities

- **Vigorous Regrowth:** Common hazel can quickly regrow from its base after being cut, a process called coppicing, helping it thrive in managed woodlands.
- **Wind Pollination Specialist:** Common hazel releases vast amounts of pollen into the air, effectively spreading its genes even before other plants leaf out.
- **Nutrient-Rich Provision:** Common hazel produces highly nutritious hazelnuts, providing essential energy and food for many animals, aiding in seed dispersal.

- **Eats:** [Eurasian Jay](https://www.snappit.app/explore/eurasian-jay) (*Garrulus glandarius*) — buries nuts for later, aiding dispersal
- **Shelter:** Hazel Dormouse (*Muscardinus avellanarius*) — builds nests and feeds on nuts
- **Eats:** Wood Mouse (*Apodemus sylvaticus*) — forages for fallen hazelnuts on the ground

## Traits

- [Deciduous](https://www.snappit.app/explore/traits/deciduous): Deciduous plants periodically shed all their leaves, typically during autumn or dry seasons.
- [Shrub](https://www.snappit.app/explore/traits/shrub): A shrub is a woody plant smaller than a tree, typically with multiple stems branching from or near the ground.
- [Spring Blooming](https://www.snappit.app/explore/traits/spring-blooming): Spring blooming plants produce their flowers during the spring season, often signifying the end of winter and the start of new growth.
- [Broadleaf Tree](https://www.snappit.app/explore/traits/broadleaf-tree): Broadleaf trees are angiosperms characterized by flat, wide leaves that are typically shed annually in temperate climates.
- [Fruit Bearing](https://www.snappit.app/explore/traits/fruit-bearing): Fruit-bearing plants produce fruits, which are the mature ovaries of flowering plants containing seeds.
- [Nut Bearing](https://www.snappit.app/explore/traits/nut-bearing): Nut bearing plants produce hard-shelled fruits, commonly known as nuts, which contain a single seed and are a valuable food source.
- [Edible](https://www.snappit.app/explore/traits/edible): Edible plants are those parts of a plant that are considered safe for human consumption.
- [Pollinator Magnet](https://www.snappit.app/explore/traits/pollinator-magnet): Describes plants that are particularly attractive and beneficial to a wide range of pollinating organisms.
- [Forest](https://www.snappit.app/explore/traits/forest): Forest habitats are terrestrial environments dominated by dense tree cover, supporting a high diversity of plant and animal life.
- [Longevous](https://www.snappit.app/explore/traits/longevous): This trait characterizes organisms with an exceptionally long lifespan compared to others of their kind.
