From Halopedia, the Halo wiki
Florus Corp was a human business on Sonata, an Outer colony world in the Helice-12 system.
The company was founded at some point before August 2558. Competitors to Florus Corp have attempted to replicate Florus Corp's florus crops through synthesized versions, but there were differences.
Florus Corp exported refined florus, a non-glucose based sweetener to the rest of human space.
