I often get questions about what and when I am planting for cut flowers in North Texas. You may not realize, but starting in October, I re-plant our fields and those plants grow all winter until Spring when they burst with flowers. In this sense, even though we're farming (growing) all winter, we don't have flowers blooming until Spring.
I direct seed some plants into the soil in late October. But some plants are transplanted: they get seeded into a seed tray in September, some even late August, and spend those months growing into a small plant. Once temperatures cool down outside, and they're big enough to survive the move, they leave their trays for the ground.
I've created a simple guide that I hope you'll find helpful in approaching fall with cut flowers in mind. This is the schedule we use for the plants we grow here in North Texas on our flower farm.
I hope this guide helps you in your fall flower planting!
Happy Growing!

p.s. An excellent book on the topic is Cool Flowers by Lisa Mason Ziegler and goes into far more detail regarding cut flowers planted in the fall.
