Devil’s backbone houseplant likes bright indirect sunlight. Plant in direct sun in fall and winter, but give it a little protection from stinging hot rays in spring and summer. Just turning the slats on your blinds can be enough to keep the tips of the leaves from sizzling.

Choose a draft free location in the home when growing Pedilanthus indoors. It doesn’t tolerate cold breezes, which can kill off the tips of the growth.
