Heat Tolerance of Barberry Plants

10 years ago

I've heard conflicting reports about the heat tolerance of Berberis thunbergii. Some people say, as I always thought, that Berberis thunbergii was extfremely heat and drought tolerant, but others say it will scorch with enough heat. Does anyone in a southern climate have any experience with barberry plants who can clear this up?
I am considering planting a Berberis thunbergii atropurpurea (red baraberry) and a Berberis thunbergii 'Green Carpet' (Green Carpet Barberry) on the south side of my house where they will get full, blazing sun from sunrise to sunset and reflected heat from the house. They will be in well-drained, sandy soil, so wet soil won't be an issue. Do you think they will scorch, or should they thrive?
