Coleus in a windowbox loving heat.
Portulaca loves the heat.Rose of Sharon bending over to the ground because of the heavy blooms on it.
Mariogolds and my little orange tiny zinnias are blooming. I grew the zinnias from seed started in the greenhouse this year (zinnias are in the back). A morning glory bloom - I've had to practice deer-protection methods on the morning glories - they are fenced in from every angle. The morning glories I grew from seed the deer don't bother (and they're not blooming yet),
Rudebeckia have really spread by reseeding themselves from last year so I have a good stand of them.
