Answer: This is actually the Meserve hollies called Blue Girl and Blue Boy. The plant's natural shape would be a dense pyramidal outline, taller than wide at first but eventually widening outward with age. This would be in a full sun location. In a shadier area the plant will not grow as solidly dense, it will stretch upward and outward for more light. It will also probably lean toward the light. With regular pruning you can easily encourage it to stay more compact if needed. These plants are relatively slow growing, in any case, so it will be quite some time before it begins to exceed the smaller dimensions. I would ultimately (in say twenty years) expect something in the range of eight to ten feet tall and six to eight feet wide.
