I did one in nellie stevens holly and it was stunning. Took a few years to grow, but NS is fast growing for a holly. Bird friendly, evergreen and super dense and tough. Drought tolerant, and I never touched the things after they were planted. They just flourished. I have many animals and no problems with that but zero goat experience. Another upside is that they are a bit prickly and stiff so discourage passing through by either larger animals or people. The first thing I bought for my new yard was seven nellie stevens, of all the zillions of plants I lost.

Also I had a couple of fence hedges using various Eleganus. They can be very nice, evergreen, thick, etc but require maintenance with either issues of pruning, scales on one, aphids. I had too much land to deal with that. I liked them but didn't love them.

Hope that helps.

I'm going to plant a screen of Wax Myrtle in the next few weeks.

I read a few threads on GW (shrubs forum and this forum i think), and chose wax myrtle because it is very fast-growing, evergreen, has berries that attract birds, is native to the SE, and looks pretty. Its supposed to do well in sun/part sun/part shade, so I'm hoping it takes off in our part-sun area.
