Mislabeled shrub

I bought this shrub when it was tiny.  It was labeled as a doublefile viburnum, which is a zone 5 plant.  But a friend who has grown doublefile viburnums (in zone 5 - she currently lives in zone 4) gave me the news that this is really a Autumn Jazz viburnum.  I was disappointed, but also glad to know that this is not the shrub I thought it was before it gets too big to move.  It will find a new home in the back border, as it will get to be over 12 feet tall.
