Answer: Night blooming jasmine is Cestrum nocturnum. Like other plants called jasmines, cestrums are extremely fragrant. Their white to greenish yellow blossoms, about 1 inch long, bloom in clusters intermittently all year, followed usually by black berries. C. diurnum, fragrant by day, has glossy 3- to 4-inch-long leaves. C. nocturnum is fragrant at night; the berries are white, the thin oval leaves may grow up to 8 inches long. All species are gangling but can be kept under 2 feet tall by periodically pinching off the stem tips.
Cestrums do best in at least four hours of direct sunlight a day, night temperatures of 60? to 65? and day temperatures of 70? or higher. Keep the soil moist; fertilize every three to four months. To encourage branching, prune old growth after flowers fade. Propagate by stem cuttings at any time. Watch for aphids, mealybugs, spider mites, and whiteflies.
