Lettuce

Lettuce for taming and salads

Lettuce belongs to the Primitive Plus DLC of ARK: Survival Evolved. Its in-game line is "Great for adding fiber to your diet!", yet a survivor who eats it gets no food points at all; the wiki suggests making salad instead. Its uses are feeding herbivores during taming and making salads.

Growing Lettuce

Plant Lettuce Seed in a Medium Crop Plot or a Large Crop Plot, and the plot produces Lettuce.

Taming with Lettuce

Like Fresh Spinach (Primitive Plus) and Fresh Sorghum (Primitive Plus), Lettuce can be fed to creatures during a tame. Each piece restores 20 food in the taming process, against 40 for normal crops such as Rockarrot. The wiki explains that a tame needs the same number of pieces either way, which is why Lettuce tames twice as fast as those crops. When the right kibble is missing, the wiki rates it the best way to tame herbivores, while warning that taming effectiveness can sink very low.

Notes on the wiki report it working on a Paracer in Scorched Earth and on an Ankylosaurus on XBOX One. Not every herbivore accepts it, though: the Kentrosaurus ignores it.

Salads, weight and spoiling

Our records list 2 recipes that take Lettuce: a Salad needs 5 and a Prime Salad needs 1. Each Lettuce weighs 0.1 and stacks to 200, for a full-stack weight of 20. The wiki infobox gives it a spoil timer, so it does not keep forever.
