I'll preface this by saying that I am not a rose kinda girl. It would be so much easier if I was but I'm not.

Colors are deep plumy purple, pumpkin orange, chocolate brown, and white. I really want a clean look so something that would look great as a single stem is a bonus.

Links to pictures would be great if you have them but not necessary.

Autumn Gerberas daisy, Chrysanthymums, pittsporum, wheat, carnations, Asiatic Lily's, seeded eucalyptus, asters,freesia, larkspur, sunflowers, Alstroemeria.
All these come in purples, and oranges, and fall colors. The asiatic Lily's can come in a really deep plum color They would be gourgeous as a center focal point.
