Lavis is grown on hillsides across Roshar.
Lavis fields are typically planted in the seasons following the Weeping, when the highstorms are weaker. A mixture of lavis seeds and stumpweight sap is spread across the hillsides. As the dark brown polyps begin to grow, they have to be wormed. Farmers must carefully go over each polyp searching for worm burrows. The worms like sugar, so they can be removed by inserting a reed tipped with sugar into the burrow and pulling it out when the worm latches on. Once the worm is removed, the polyp can be patched with crem. Each field can take weeks to check and it is important to check repeatedly for worms since any worm that is missed results in the loss of the entire polyp. The crop can be fertilized during the worming process.
Mature lavis polyps are filled with grains suspended in a sandy material. They are broken open, and the grain is separated from the grit and typically dried for storage.
There are different strains of lavis. The variety grown in Hearthstone has polyps that grow larger than a man's head and mature in about four months. There are smaller, heartier strains that can thrive in regions where the highstorms are stronger. 
Lavis is a staple food source and is prepared in many ways.
Lavis grain is the basis of the economy in many small towns like Hearthstone. Sebarial considers it a lucrative enough crop to include as an important part of the economy he builds in his warcamp on the Shattered Plains.
Lavis grain typically goes through several merchant middle-men on its way from the farming communities to the cities. By the time people buy it in the city, it usually costs four to five times as much as the farmers sell it for.
