Monarda_didyma , aka bergamot.

A question about the word didymous. Would the monarda be named didyma because the flowers are bilabiate?

"Monarda / Oswego Tea comes from the Oswego Indians who taught the immigrants how to use it for tea after the Boston tea party in 1773. The flowers and leaves are good ingredients for potpourri making. Note that the bergamot herb is not the source of bergamot oil, used to flavor Earl Grey tea; that comes from the bergamot orange, a Mediterranean citrus fruit."
