I like the Nellie Stevens Holly. I planted five of them on our property last spring and am going to be planting more of them this fall. They will get large over time, but from what I researched, they are a slower growing tree than a Cryptomeria Radican, Green Giant Arborvitae, etc. I think they grow more like 6"-18"/year (I've seen the growth rate listed as high as 3 feet/year, but don't believe it, perhaps in IDEAL conditions). The other two I mentioned supposedly grow around 3-4 feet/year. From what I have read, they don't grow at that rate for the first 1-3 years though. They spend the first couple of years spreading their roots, then shoot up. I planted 8 Cryptomeria Radicans and two Green Giant Arborvitae's this past fall, so will report back in a year or two, lol. I am going to plant about a dozen more of the Cryptomeria this fall.
