I do remember planting two at the same time and only one has survived. It has done MUCH better since we removed a Mountain Ash tree and a pyramidal juniper that were close to it and it gets more light. It looks quite white in the picture but is actually pale blue or mauve.

I'll keep looking for a better picture of it close up.
