Picea purpurea: Anyone growing this in Zone 4 or 5a?
A local nursery just got a shipment of these from Bizon and I'm sorely tempted to try it. It has an extremely dense, pyramidal form and produces beautiful purple cones (hence the name).
What gives me pause is the online descriptions variously rate it to either Zone 4 or Zone 5. Given that its native range is Sichuan/Gansu, China, I'm not sure how well it would handle a brutal Midwest winter like the one that just transpired.
Does anyone have experience growing P. purpurea (formerly Picea likiagensis var. purpurea) in Zone 5a or colder? Also, the online descriptions of its 10 year height range from 4 feet to 8 feet. What's your experience?
