With its heart-shaped leaves, twining vines and flowers the hue of the heavens, Ipomoea tricolor ‘Heavenly Blue’ is a striking plant that has withstood the test of time. This stellar specimen is a native of tropical America, with records of it arriving in Britain in 1629. According to “100 Flowers and How They Got Their Names” by Diana Wells, there’s good reason to be awestruck when it comes to a morning glory. She writes, “ … Looking at it from above or below, morning glory always twines clockwise or counterclockwise around its support. However you see it, the direction does not vary, regardless of heat, cold, light, climate, or even hemisphere. It is genetically programmed.” Morning glories couldn’t be easier to grow: direct seed in spring, either soaking the seed before planting or scarifying it (nicking through the tough outer shell of the seedcoat with a knife). The flowers last but a day, opening in the morning and often fading away by afternoon, its fleeting beauty making it all the sweeter.
