Several types of night flowers bloom only during the night hours instead of during daylight hours like most plants. Some night flowers open in the dark and remain closed in the sunlight, others emit a fragrance that attracts moths and bats, and some do both. For a scented experience and open flowers during the night hours, add night flowers to your garden.
Angel's trumpets (Burgmansia solanaceae) are hardy plants with night-blooming flowers; flowers remain open until dawn, according to the AgriLife Extension Bexar County. Displaying elongated trumpet-shaped flowers in pink, yellow and white, angel's trumpets release a pleasantly perfumed fragrance. Ideal growing conditions for angel's trumpets include warm to hot temperatures with consistent watering. Thriving in full sun to partial shade, plant angel's trumpets in fertile, well-drained soil and watch them grow to a height of 8 to 10 feet. Practice caution when gardening with angel's trumpets; these night-flowering plants are considered poisonous, as consuming large amounts of the plant can lead to illness or death.
Flowering tobacco (Nicotiana) is a plant with night flowers that releases a fragrance at night. Flowering tobacco plants display flowers in a variety of colors, depending upon the cultivar; colors include pink, red, purple, rose, white, multicolored and pale green. Erect, annual plants with trumpet-shaped flowers, flowering tobacco plants prefer full sun, are tolerant to partial shade and thrive in moist, well-drained soil, according to the University of Illinois Extension. This night flower grows to a height of 1 to 4 feet.
Plantain lilies (Hosta platnaginea) are flowers that blossom open at night. Known for their strong, pleasing fragrance, plantain lilies are tolerant of heat and sun, thriving in shade or sun that lasts up to three quarters of a day, according to the Clemson University Extension. Plantain lilies prefer well-drained soil and display large white flowers and green foliage. Cultivars of plantain lilies are well suited to the climate of the South where they grow up to 24 inches in height and 38 inches in width.
