You just credit the climate for killing them?
They just fry in the dry sun I guess huh...
Texas sure seems to have had it rough weather wise lately...
I guess it unforgiving territory...
Orinoco might be a good choice for you...
Have you tried growing any in big pots?
Atleast when the ground is so super dry that it wicks all your watering away, you could keep a pot wetter easier, and if it got so hot you could possibly move then to some shade...
