Overview
Fast-growing climber. 4-5" trumpet-shaped flowers are vibrant sky blue with creamy white throats. Lovely heart-shaped foliage and fast-growing vines are excellent for arbors, trellises, or as a ground cover. Easy-to-grow heirloom variety. Flowers open in the morning and close in the afternoon. Morning glory requires short days and long nights to trigger flowering. Vigorous plants put on lots of growth through the spring and summer and begin blooming in midsummer, producing continuously through early fall. NOTE: plants grow vigorously and have the potential to reseed.
