Your orange-yellow, Lorn, looks like calendula. They are supposed to like the cool weather.
Myself, I can't get excited about gladiolus, but culturally (care) wise they would be great matches. Nope, can't get excited, unless they are species glads, of course.
The idea of using reseeding annuals is a good one. Then you pull out the ones you don't want and leave those that decided to seed in the right places. I do this with a number of things for several reasons. Favorites are Negella hispanica, Ruellia humilis, Imatiens balfourii, Aquilegias, Black-eyed Susans.
I can't believe anyone hasn't taken up Jo Ann's statement that winter is here. Are you nuts? (Says the man nutso about underground bulb structures.)
