How much light is available in your planned location and how soon do you need them to be at 5 or 6 ft? Here's an [older thread that discussed several options[(https://www.houzz.com/discussions/austin-suggestion-for-fast-growing-everygreen-shrub-dsvw-vd~2198833).

There are several hollies, boxwoods, nandinas, and others that could provide that screening in sun or shade, but would take many years to reach ~6 ft from one or two gallon starts. Could plant canna (or similar) behind slower growing shrubs for quick 5 ft cover during the growing season while the slower evergreen plants get going.

Shiny xylosma (Xylosma congesta) might be worth a look in your area. No experience with it, but appears to have fewer flowers than many alternatives and grows a couple feet per year once established.

Red-tip photinia (Photinia × fraseri) are inexpensive and very fast growing, so still useful as a temporary screen. They do flower, but don't recall much of a fragrance. We have several nice (though now massive) examples surviving in our ~50 year-old neighborhood. Main problem is the heavy pruning often needed to keep them in bounds once they mature makes them much more susceptible to disease. Suppose another question is whether you want to plant something for future residents or a quick cover you'd be happy cutting down as you leave.

There should be plenty of sun, Its an open area with no tall buildings or trees. I appreciate all your advice. I did a ton of exhausting research yesterday and ended up picking up a couple shrubs at Walmart, boxwood and holly.. but i know they are kinda slow growing...

Also I need to edit my post a little I think.

I want to put them into very large tubs/planters because as a renter I can't really change the lawn. Because the tubs are already like a foot and a half tall, I would be able to have the privacy height with a 4 foot plant.. which makes me feel better about the growth rate.

I'm liking the idea of having a mixed hedge, i think the different plants will look more interesting, i'm a big nature/wilderness lover and this way i can get experience with multiple plants and see how they grow.

I think I really want a 'arborvitae' too, (like an emerald green or something) i know a lot of people hate them. but i'm thinking just get one. i know they grow really tall but I stay home and have no issue with doing the maintenance, and I would trim it into a hedge shape..

Mixed hedge does sound like a better and more flexible option. My container grown plants are usually in the ground or dead beyond 2 gallons. Hopefully someone will comment on what it takes to raise and maintain outdoor container plants to the size you need in central Texas. Best of luck with them and let us hear how things turn out.
