Tripleurospermum Oreades Tchihatchewii is a mouthful of a name, so it's no surprise that people might be looking for some synonyms. One possible synonym is Matricaria maritima, which is a related plant with a similar appearance. Another option could be the common name Sea Mayweed, which is often used to refer to several different species in the Matricaria and Tripleurospermum genera. Some other synonyms that might be relevant include Chrysanthemum oreades and Chrysanthemum tchihatchewii, which were used for this plant in the past before it was reclassified. No matter what you call it, this is a hardy and beautiful wildflower that can liven up any landscape.
