Hello everyone!
I'm pondering planting some sky pencil holly shrubs/trees staggered behind my emerald green arborvitae trees in case I lose one of them. When I research SPH, it says they are far zone 5, but it says hardy to -10*. Does anyone here have experience with SPH, and can they withstand colder than -10*? We do seem to have milder winters here (over the last 15-20 years), but occasionally, with W. chill, it can go down to -30 to -40 below. I just don't want to plant them and then have them die. Thank-you for all information.
These would be planted on the east side of our property.
