Carnations are the official flower of Mother’s Day because they were a favorite of Civil War community organizer Ann Jarvis, whose daughter is credited with founding the holiday. Roses are also considered traditional, though red isn’t recommended as it represents romantic love. Tulips are very popular in the spring when Mother’s Day takes place, and orchids are commonly gifted because, in addition to being striking, they make for low-maintenance houseplants that will live long past Mother’s Day.
