Hi Everyone, I found this site a short while ago and wow, so much information! I have been lost in here for hours!

I am new to gardening in Dallas TX (just south of down town Dallas) and came from St. Pete Florida. All of my gardening experience is in Florida so I am learning about cooler weather gardening. I have been researching plants and in the middle of a back yard redo. I am looking for a hedge plant or small tree that is evergreen, good for privacy and does not get taller the 20 ft or so (powerlines above the back fence) You will see from the photo I am desperate to hide my neighbors unsightly structures! the bed(s) that they will be going in is 8ft deep and spans about 40 ft.

I am thinking of using Wax Myrtle or Hollies (unsure of which one still researching what will work and not be thorny) along the back fence . Or a combination of a few types of trees/shrubs. I am thinking that I would trim the shrubs in to a tree form to be able to do light planting under them

Would anyone have a suggestion of other shrubs or small evergreen trees?

Thank you in advance,

Duff
