What are types of flowers that are considered "fall"?

Question

I am looking for medium orange, darker burgandy, and ivory flowers that are considered in season in the fall. They would be used for wedding bouquets. I'm not a fan of roses. The more unknown and unusual, the better.
A florist will be consulted when I have a better idea of what I want.

I'd like to apologize ahead of time if this is under the wrong category. I didn't want to post it in the wedding category as I am looking for types of flowers and plants and not necessarily what others have used or what is "pretty."

Fall blooming plants include asters, dahlias, chrysanthemums, blue flowered Caryopteris, & colchicums that look like crocuses.

Sometimes called Autumn Daffodils, the sternbergias come in yellow or gold.

Any Autumn Sage like Salvia greggii ‘Furman’s Red’.

Blue statice and sunflowers are lovely but apricot statice and chocolate burgundy sunflowers would be stunning.

Or the orange pansy's, they have a fall like color to them also, and if this is for a wedding, you could even cook them/sugar coat them etc and spread them around, they are edible
