What are the meaning of perennial crops and the examples?

Perennial crops are plants that live for more than two years and can be harvested multiple times without needing to be replanted each year. These crops have deep root systems that allow them to survive through multiple growing seasons. Some examples of perennial crops include:

1. Fruit trees such as apple, pear, and cherry trees
2. Nut trees such as almond, walnut, and pecan trees
3. Berries such as blueberries, raspberries, and blackberries
4. Grapes for wine production
5. Asparagus
6. Rhubarb
7. Artichokes
8. Bamboo
9. Turmeric
10. Vanilla orchids

Perennial crops are beneficial for sustainable agriculture as they require less labor and resources compared to annual crops, and they help improve soil health and prevent erosion.
