@Totally_Amazing, Robin, FFO does mean first flower open in a person's garden. Most folks are pretty excited when each daylily cultivar first opens in their garden for the season. Then the next year, we are just as excited to see the ffo again on each cultivar, lol!
If you want to really delve into the nomenclature of the daylily language, attached is the AHS website's Dictionary of Daylily Terms.
