Looking for plant suggestions for the following area:

- location: northern suburb of Dallas, TX
- two concrete pots, approx. 14" diameter, 13" tall, on front porch
- mostly western exposure - very hot sun in PM!
- porch is covered, i.e., no natural rainfall and shade until afternoon
- filled pots are too heavy to move and have no place to give them better protection, so need some cold tolerance as well

Would like a perennial, 2'-3' tall, fairly narrow, upright habit. Does not need to bloom, but would like something that looks good year-round.

Any ideas? Thanks for your help!

You might look at some of the herbs. I have some upright rosemary plants in similar conditions to what you have. They are pretty tough, tolerate some shade, and are a ready supply of culinary seasoning. It's nice to have them where you brush by them and get a fragrance bonus.
