My great-grandmother’s “night blooming Cereus” (Epiphyllum oxypetalum), with its long, flattened, sword-like leaves, was a cause for family gatherings when it started to flower at night. Mine was grown from an easily-rooted piece of leaf stem from her original plant. Other commonly-shared night flowering cacti include those with three-sized leaf stems (Hylocereus) and rounded leaf stems (Selenicereus).
An intense and intoxicating perfume wafts from the flowers of night-blooming jasmine each evening. Plants blossom intermittently year-round and grow rapidly. Prune as needed to retain shape. Just make sure not to prune too often, since flowers form on mature stems. Give this plant a sunny southern window for best flowering. Botanical name: Cestrum nocturnum
