I lived in the south a few number of years and became accustomed to the American Holly and wanted to plant one in zone 5a. Some opaca around here lose thier leaves in severe winters in exposed sites but recover soon as spring hits so in zone 5 these guys are fully usable. Others never lose a leaf. Winter protection can always be useful this far north for a better looking plant but not necessary.

The American Holly is very nice, broadleaf-evergreen tree native north to coastal portions of Connecticut on the east coast. Trees from native stands here in Connecticut often have a very pleasant, slightly conical (like the Southern Magnolia), open habit. This plant is underused in landscapes across the northern part of its range. Some ignorantly insist that the tree, though native here in the northeast, is not "hardy." It would be nice to see more of these trees and less of the overused China Girl or China Boy hollies.

I love this holly, so much prettier than the other hollies because it doesn’t lose all of it’s leaves like the other ones, it does shed and those prickly leaves everywhere but you can never see all the way through it like some others. Ours is close to 30' I'm sure, and my favorite tree in the whole yard!

American holly is an excellent broadleaf evergreen for the Ohio River valley region, and everywhere its wide native distribution allows it to grow (northeastern US down the Atlantic coast and through most of the south).
Typically conical in habit, American holly can be pendulous, columnar, or a dwarf spreader. It is normally red-fruited, but there are fine orange and yellow-fruited forms too. There are selections made for zone 5 winter hardiness, and trees selected for virtually spineless leaves. Over one thousand cultivars have been named, so there is pretty much an American holly for everyone.
Peruse the cultivars illustrated in PlantFiles, and see if you don't find one that deserves a place in your landscape.

I think this is my favorite of the hollies. There is at least one of them planted where I am living now. Seems like they maintain a neater, more conical growth shape, more leaves, a darker color green and detailed leaves. I'm glad to see quite a few of this native in my new area.
