A genetically engineered species of grass unique to the desert moon, Seharia. It is rich in natural sugars, including sucrose, maltose, fructose, and glucose, as well as polysaccharides such as starch and glycogen, which it stores in its roots and mature stems. Duolon is harvested at the two extremes of its growth cycle - right after sprouting, and when it is very mature. Both stages of the plant are used for producing food products. Duolon shoots are known throughout the Terran diaspora for their use in producing Seharian Duolos, a very strong beer with questionable (and in some places illegal) additives.
