Most morning glory flowers unravel into full bloom in the early morning. The flowers usually start to fade a few hours before the "petals" start showing visible curling. They prefer full solar exposure throughout the day, and mesic soils. Some morning glories, such as Ipomoea muricata, are night-blooming flowers. 6park.comIn some places, such as Australian bushland, some species of morning glories develop thick roots and tend to grow in dense thickets. They can quickly spread by way of long, creeping stems. By crowding out, blanketing and smothering other plants, morning glory has turned into a serious invasive weed problem. 6park.comIn cultivation, most are treated as perennial plants in frost-free areas and as annual plants in colder climates, but some species tolerate winter cold. There are some species which are strictly annual (e.g. Ipomoea nil), producing many seeds, and some perennial species (e.g. I. indica) which are propagated by cuttings. Some moon flowers, which flower at night, are also in the morning glory family. 6park.comBecause of their fast growth, twining habit, attractive flowers, and tolerance for poor, dry soils, some morning glories are excellent vines for creating summer shade on building walls when trellised, thus keeping the building cooler and reducing heating and cooling costs. 6park.comPopular varieties in contemporary western cultivation include 'Sunspots', 'Heavenly Blue', the moonflower, the cypress vine, and the cardinal climber. The cypress vine is a hybrid, with the cardinal climber as one parent. 6park.com贴主:jmzjmz于2021_05_09 14:45:20编辑
