At our home, we have a very wide overhang which never sees any moisture, so we were looking for plants that would stay low, ideally evergreen, and would tolerate seriously dry shade. The answer was Echeveria ‘Topsy Turvy’. These patches of the Northern Mexican succulent, with blue-green foliage, have absolutely thrived here. While they probably wouldn’t be happy in deep shade, they love this high canopy with good light, but no sun. These were planted in 2018. We’d rate these as Zone 7b/8a if kept dry in winter.
