out of curiosity, I went and looked and all I could find were ferns. But as to your question, there aren't many. dwarf podocarpus, or reg. podocarpus that will require pruning to fit your required space. dwarf false hinoki cypress, dwarf cypress. Overall, just not that many for our area.

You might like the long leaf pine. It starts looking like a clump of grass

Then becomes an oddball looking plant. When it outgrows your space

Remove it.

Thank you both--good ideas!

I'm in Houston. What did you end up planting in your space ibseyb
