What is best plants to plant in Texas for a privacy screen?

For starters, let me introduce you to our Native Plant Database which will help you select plants for your situation. The Database contains 7,161 plants that are searchable by scientific name or common name. There are several ways to use the Database, but we are going to use the Recommended Species List. To do this, go to the Native Plant Data Base and scroll down to the Recommended Species List box. Clicking on the map will enlarge it so that you can click on East Texas. This will bring up a list of 133 commercially available native plant species suitable for planned landscapes in Texas. That is probably too many, so you can go to the "Narrow Your Search" box on the right of the screen and make the following selections: select Texas under State, Tree under Habit, and Perennial under Lifespan. Check Sun under Light Requirement, Dry under Soil Moisture. Click the Narrow Your Search button and your list shrinks to ten species. Notice that there is now a Leaf Retention category in the Narrow Your Search box. Check Evergreen and then click the Narrow your search button, and your list shrinks to four species.
