I'm sure that someone in your area/zone will chime in but I have found that plants really need at least 2 seasons here to see the true look. The first season blooms may be good and look the way they should but they really amaze me the second bloom season. Now in your area it may take a little longer but I don't know. But if you have to wait 5 years or 10 years for a plant to perform at it's best then I wouldn't have it.
