Flowering cacti and yuccas

Thread leaf yucca (Yucca constricta)

Spanish Dagger (Yucca).
The Spanish Dagger (USDA Plant database) and Texas A&M database),
like all yuccas, depends on the yucca moth as its sole means of fertilization.
In turn, the yucca moth, Pronuba, depends on the yucca
as the only place where its larvae can mature.
