Floriculture was discipline of horticulture that focused on flower breeding and cultivation.
Tuvok was previously a breeder of prize Vulcan orchids, prior to USS Voyager being stranded in the Delta Quadrant. It was because of this background that he was able to correctly identify a rare variety of Earth Cypripedium, of the Asiatic genus Paphiopedilum, found on the Sky Spirits' homeworld in that quadrant.

Tuvok shared his floricultural interests with Lon Suder during a mind meld. As a result, Suder took his newfound interest in the science and made it his own by developing what he named the "Tuvok orchid". (VOY: "Meld", "Basics, Part I")
