I need a better pic. I could actually see it being all three that have been mentioned. The pictures shows a Red tint on my on my computer which would make me think Loropetalum or Barberry. But if they do not have thorns then I would rule out the Barberry. In my area the Loroletalums do not have that dense of branch structure on the interior. Now if the areas that look to have a Red tint are actually more Brown then I would say Dwarf Yaupons, because of the very dense interior branch and leaf structure. Like I say, I would need a better pic or see them to be for sure, but the tight and dense branch and leaf structure on the interior makes me think these are Dwarf Yaupons with freeze damage on the outer more tender leafs.
