I'm testing out which plants will thrive on the sunny side of my house where they receive 5+hrs of direct sunlight. I've tried a Crape Myrtle, Hydrangeas, a Gardenia, Butterfly Bushes and Knock-out Roses and water them as per instructions. All wither or die except the roses. Are they dying because they're still in POTS, or do I need to try different plants?

I think they are dying because they are in pots rather than planted in the ground. The roots in pots that are exposed to hot afternoon sun can actually bake. So, to further your experiment, try sinking the pots into the ground. The soil will help insulate them from the intense heat. Water as usual and they should thrive, with the exception of gardenias and hydrangeas (they like morning sun and afternoon shade). Best wishes with your experiment.
