A type of decorative plant used in agriculture or horticulture, or possibly a musical pipe made from corn stalks.
From 'corn' plus 'muse' (unclear etymology; possibly from a dialectal or regional term). This appears to be a rare or archaic term with uncertain origins, possibly from agricultural folklore or regional British English.
Cornmuse is so obscure that it may be a ghost word—a term that entered dictionaries by mistake and then got perpetuated forever, making it a fascinating artifact of how even experts copying earlier references can cement nonsense into the historical record!
