Characteristics of Lettuce
Lettuce exhibits several unique characteristics:
- Leafy Green: Lettuce is primarily grown for its leaves, which are consumed fresh.
- Varieties: There are multiple varieties of lettuce, including leaf, romaine, butterhead, and crisphead (iceberg).
- Nutritional Value: Lettuce is low in calories but rich in vitamins A, K, and folate, and provides a good source of dietary fiber.
- Growth Habit: Lettuce grows as a rosette of leaves close to the ground, and some varieties form heads.
- Cool-Season Crop: It thrives in cooler weather and can be grown in spring and fall in most regions.
- Flowering and Seed Production: Lettuce produces yellow flowers that develop into seed heads, but it is usually harvested before this stage for consumption.

- United States: California and Arizona are the leading producers.
- Europe: Spain, Italy, and France are major lettuce-growing countries.
- Asia: China is the largest producer globally.
- Australia and New Zealand: Significant production in temperate regions.
