I have had Final Touch since 2003. I also love the fact that it is a bi-color and that it is a later bloomer in my garden. It is planted in a semi shaded location so it has not increased as well as maybe it could. The scapes have also not ever reached their registered height of 32" here, but that is also possibly related to it being in a semi shaded area. This plant is definitely coming with me on our move north. I think it will do just as well in a colder zone as it does here. It is fertile both ways and have set an average amount of pods on it.
