In the bed pictured below I wanted asian jasmine. But the problem I have is that EVERYONE around here uses it for the same purpose. I'm trying to be a little different here. I plan to have it growing down into the ditch to hold the dirt and hopefully smother out some weeds. Around the perimeter I plan something simple like boxwood and maybe a 6' crepe myrtle.

I was looking at the one at this link:

VINCA minor (Periwinkle). but it says part sun to shade... I'm afraid it will burn up in the texas heat. Is there something similar that can work for me here?
