Certain flowers bloom at designated times during the day. Some flowers only open their buds in the morning, such as the morning glory. Nighttime inflorescences are usually flowers with an intoxicating essence. Brazil is home to numerous tropical flowers with exotic aromas; several of these flowers only blossom during the evening hours. These fragrant flowers vary in appearance and color, but share a common nocturnal link.
Brazilian jasmine (Jasminum fluminense) is an invasive evergreen vine that was first documented in Brazil, yet it is also a native plant in Africa. This creeping vine can reach lengths of up to 36 feet. The dark green foliage of the Brazilian jasmine plant has leaves that are an oval shape with a broad width. These leaves grow on a stem that is 4 inches long, and each leaf stalk is 2 inches in length. The flowers of this plant are small, droopy, star-shaped blossoms that have five narrow, elongated petals, yet are only about 1 inch in length. The inflorescence form in clusters and are a pure white; these flowers only open during the nighttime and release their cloying aroma into the air.
Angel's trumpets (Brugmansia suaveolens) are located in Southeastern Brazil; these flowers are also found in parts of South and Central America, Mexico and Florida. This woody shrub or small tree grows to be 6 to 15 feet in height. The blooms are pendulous trumpet-shaped flowers that reach up to 12 inches in length and are 4 to 6 inches wide. Angel's trumpet has enormous flowers that are usually yellow, white, orange, red, purple or pink in color and blossom nightly with a light sweet scent. The evergreen leaves of the plant are long ovals about 6 inches in width and 10 inches in length. The leaves are coarse in texture and shaded a dark green. The shrub blossoms open during the summer and continue into the fall. Unfortunately, all pieces of the plant are poisonous to humans because of its narcotic qualities.
Four o'clocks (Mirabilis jalapa) are native flowers to Brazil and other countries in South America. These flowers have been introduced into the southern region of the United States and can be seen in the gardens of Thomas Jefferson at Monticello. The four o'clock is a trumpet-shaped flower that is 1 inch across and about 2 inches in length. They bloom in one solid color on a multi-branched leafy shrub; on rare occasions, some flowers will be multi-colored. The flowers are generally red, pink, white or yellow. This perennial plant is 24 inches in height and explodes into bloom during the spring until late into the fall season. The Brazilian native has a sweet bouquet that is released into the late afternoon and evening air; it has a distinct scent that is likened to the jasmine flower.
