Lettuce

Lettuce is a food item farmed by the Hobbits of the Shire and can be found there as loot in various structures, from the larders of Hobbit Holes to the fields of Hobbit farms. They are also available for trade from various Hobbit traders.

Farming
Lettuce can be planted on farmland and grown as a crop, in the same way as other seedless crops like carrots and potatoes are grown. Be mindful where you plant them however, as rabbits lucky enough to find them (with easy access to the farm) will eat them.
