Characteristics of Cashew
The cashew tree is known for several distinct characteristics:
- Growth: Cashew trees can grow up to 14 meters (46 feet) tall, but dwarf varieties reach around 6 meters (20 feet) and are more commercially viable due to their ease of harvesting.
- Leaves: The leaves are spirally arranged, leathery in texture, and elliptical in shape.
- Flowers: The flowers are small, with a pinkish hue, arranged in a panicle inflorescence.
- Fruit: The cashew fruit consists of two parts: the cashew apple and the cashew nut. The cashew apple is a swollen, fleshy pedicel, while the cashew nut is a kidney-shaped drupe attached to the end of the apple.
- Nuts: The cashew nut is encased in a hard shell that contains an allergenic phenolic resin called urushiol.

Cashew trees thrive in tropical climates with a dry season that allows the nuts to mature properly. They are primarily grown in regions such as:
- Brazil: The native habitat and one of the largest producers.
- India: A major producer and exporter of cashew nuts.
- Vietnam: Leading in cashew nut processing and export.
- Africa: Countries like Nigeria, Ivory Coast, and Tanzania have significant cashew farming industries.
- Southeast Asia: Including countries like Indonesia and the Philippines.
