The Friendship of the Trillium was given to those who had consistently lent support and guidance to the Coronet. Upon retirement, the consort of Ealdormere became a member of the Friendship, but membership was not restricted to past consorts. Members, called Friends of the Trillium, may place the initials FT after their names, and may wear a medallion bearing the order's badge: Purpure, a trillium argent barbed and seeded vert within a bordure embattled argent.

Along with all of the other awards given by the Principality of Ealdormere, this award was closed on October 17, 1998 in preparation for Ealdormere's transition from Principality to Kingdom.
