Answer: I think a local nurseryman would have accurate knowledge about the growth rates and habits of junipers in your region. Catalog descriptions are based upon ideal growing conditions in terms of climate, soil and water availability. If your growing season in shorter, or temperatures are above 90F much of the time, the plants will not grow at the same rates as they might in mild climates such as California. I'd tend to trust the nursery professional's advise.
