We are just a few miles away from each other. A Zepherine Drouhin climbing rose would do well in shade if you like roses. Good fragrance and very few thorns, too. Planted one at my sister's (also in Garland) and it thrives. June and Mighty Mouse Hostas did really well for me the last two years with very little supplemental water. Could also try Hellebores, Scabiosa, Indian Pink, and/or Veronicas.
