In my hot, sunny yard there are several cuphea that bloom heavily all summer and are also hummingbird and butterfly attractors. In the Charleston area they die to the ground every winter but are always in bloom again by the time the hot weather kicks in and continue blooming well into fall as you can tell by these pictures taking on October 23. These two cupheas are both commonly called Cigar Cuphea but are different varieties - one large and one small. The orange flowers of both are toned down by their maroon stems and dark green leaves which I think rescues them from the brink of gaudiness.
Cuphea ignea, one of several plants commonly called firecracker plant, is the shorty of the two. Mine has never gotten over about 18 inches tall but then again it has had to survive on rain water for survival and is planted in almost pure sand. I'm not always a good plant mom!
