Alstroemeria; aka Peruvian Lily. As I was reading up on this guy I
came across the following passage in Wikipedia, which you can see
demonstrated in the picture.

"Perhaps the most fascinating- and telltale- morphological trait of
Alstroemeria and its relatives is the fact that the leaves are
resupinate, that is, they twist from the base so that what appears to
be the upper leaf surface is in fact the lower leaf surface. This very
unusual botanical feature is easily observed in the leaves on cut
flowers from the florist."
