Autum sweet peas?

A plant that's done dreadfully badly this year is sweet peas. 

My early ones didn't work and the later ones stopped growing when it got too hot for them.

Most plants have suffered from powdery mildew and aphids but now that temperatures are cooler, I've started to see new green growth and the first flowers. 

It would be the first time I've had sweet peas in the autumn, I can't wait to see what happens...
