I have a red Esperanza, Bells of Fire I believe. It is a lovely graceful plant with bright red flowers that my hummers loved. I haven't seen too many bees on it, they are enamored with my yellow one. This is its first year in the ground and it was recommended by Texas A&M which is why I went hunting for it.
If I remember right, it should get five to six feet tall, will bloom aggressively since it doesn't set any seed till very late in the year.
