Morning Glory: A Field Guide
Morning glory vines can grow as much as 15 feet in a season, to blanket an ugly fence, wall, or telephone pole. In addition to the purple cultivars everyone thinks of when they think of morning glory, the vines’ trumpet-shaped flowers can bloom in many shades of pink, blue, white, red—as well as variegated combinations.
Some of our favorite varieties are Ipomoea tricolor ‘Heavenly Blue’ (“a classic heirloom that produces sky blue flowers with white centers,” writes our contributor Jeanne Rostaing; Ipomoea nil ‘Scarlett O’Hara’ with red flowers that attract hummingbirds, and I. alba ‘Giant White’ with perfumed white flowers that open in the early evening.
Tip: Purple morning glory (Ipomoea purpurea) has a reputation for escaping from gardens to naturalize all across the U.S.; other species are also considered invasive in some areas. Prevent it from self-seeding by deadheading flowers after they bloom. Remove the entire plant after the first frost kills it (as if it were a weed) and bag it for removal instead of putting the vines into the compost bin.
