Favinit plant

From Memory Alpha, the free Star Trek reference.

Favinit plants are a variety of flowers native to Vulcan.

Tuvok once created a hybrid of a South American orchid and a Vulcan favinit plant.

At first, the hybrid was sickly, but after a few weeks both plants adapted to their new condition and became stronger than either had been alone. (VOY: "Alliances")
