What is the species?

I can't find a plant by that name

When I lived in the Austin area, our Esperanza would die back in the winter. I would cut it at ground level, then it would come back in the spring. If you keep it pruned - especially the dead flowers, you'll have a continual flow of new flowers. However, it is a large shrub, so if it is too large for your space, you ought to move it and put something in that is a better size at maturity.
