People stay up at night to enjoy the opening of the flowers of the tropical wonder Epiphyllum petalum, better known by its common name, queen of the night flower, or orchid cactus, not to be confused ...

Cacti are known for their prickly exterior. But not so much for their flowers - except for Christmas cactus, of course.

Cactus Flower drags, which is probably the worst thing that can be said of a light comedy. It's due to sloppy direction by Gene Saks and the miscasting of Walter Matthau opposite Ingrid Bergman.
