Antarean basil
Antarean basil was an aromatic edible plant with dark purple leaves that was used as an herb.

On Nepenthe, Antarean basil grew "like weeds" around the home of William Riker and Deanna Troi, due to the regenerative properties of the soil. In 2399, Riker made pizza with tomatoes, Antarean basil, and bunnicorn sausage for his family, Jean-Luc Picard, and Soji Asha. ()
