Moonflower is an attractive flower in the morning-glory family. It is a climbing vine that may grow 10 feet (3 meters) high. Its broad, heart-shaped leaves block sunlight and make an excellent screen for porches. The moonflower’s pure white trumpet-shaped flowers may be 3 to 6 inches (8 to 15 centimeters) across. These strongly scented flowers open at night and close in sunlight. The moonflower grows quickly. The parts of the plant aboveground die every year, but the roots remain alive. New parts grow from the roots each year.
