Generally grown as a hardy annual, lettuce is easily cultivated, although it requires relatively low temperatures to prevent it from flowering quickly. It can be plagued by numerous nutrient deficiencies, as well as insect and mammal pests, and fungal and bacterial diseases.
Lettuce is a rich source of Vitamin K and Vitamin A, and a moderate source of folate and iron.
