Whomever posted the reply that cited "horticulturalists" having said that there is no such thing as an orange daisy is 168% wrong.
As of this date there are over 168 known varieties of orange daisies...as with most flowers the colors hue and brightness vary from the outside edge of the blossom to the center, so there is no one variety whose color exactly matches the official UT orange (it is copyrighted and registered). Seen from a distance (such as a classroom) a field of several different varieties of daisies could and probably do appear like an "orange field".
The selection of the color orange has never had anything to do with any "secret" societies, or such. What a load of bunk that is!
