What flowers did Romans use in temples? in Templum Romae - Temple of Rome Posted May 6 · Report reply I was wondering which variety of flowers the ancient Romans used to decorate their temples? I have been to India and saw that they put marigolds everywhere around temples, often in offering bowls or floating on water. Interestingly the scientific name of marigold is tagetes, which owe its name to Tages, an Etruscan god adopted by the Romans and later said to be one of Jupiter's grandsons. Does that mean that marigold could have also played a role in Roman religion? What about other flowers?
