Morning Glories are one of the easiest annuals to start from seed. In some areas, they will re-seed from last years dropped seed and some varieties may even be perennial in mild climates. After an overnight soak in water, plant the seeds about 1/2 inch deep and then stand back and watch! Best started in fertile soil with adequate moisture during germination and early growth, morning glories can produce vines up to 15 feet long and will clamber over gazebos, fences and trellises with their twining limbs. Some gardeners even grow them up a downspout and along a roof line or up into the limbs of a tall tree. They can be so vigorous as to choke out other plants nearby and can be vigorous re-seeders which grow best in average soil and full sun. They are called “morning glory” because they bloom early in the day and the petals deflate and fall off in the evening. The Morning Glory was first cultivated in China for its medicinal uses, due to the laxative properties of its seeds. It was introduced to the Japanese in the 9th century, and they were the first to cultivate it as an ornamental flower. The Japanese have led the world in developing varieties and the colors range from blue and pink to red, purple, lavender, white and even brown. The flowers are attractive to hummingbirds, butterflies, and bees.
Heavenly Blue Morning Glory (also called Clarke’s Heavenly Blue) blooms with 5-inch flowers all summer and is an heirloom variety dating back to the 1920’s. It is a lovely blue with a white center. These are one of the most easily recognized and popular of all morning glory varieties and can be up to 12 feet long. The foliage is an attractive heart shape.
Grandpa Ott’s Morning Glory bears velvety deep-purple flowers with red stars at their center. This self-sowing annual was originally grown by Grandpa Ott, a Bavarian immigrant, who lived on a 40-acre farm in St. Lucas, Iowa and was preserved by the family in conjunction with the Seed Savers Exchange. This one can climb to 15 feet tall if given support to grow on. Grandpa Ott’s grows very quickly, spreads easily and looks stunning. It will also adapt to part shade.
Although called “morning glory” the Moonflower will start to bloom in the late afternoon and close in the morning light. If the day is overcast or cool and cloudy they may stay open for a longer period. Moonflower is fragrant enough to perfume the air within 6 feet of the blossoms and loved by hummingbirds and night moths, including the large Sphinx Moth. The blooms are 5-6 inches across and the vines can grow up to 20 feet. They are native to tropical and subtropical regions of the New World, from northern Argentina north to Mexico and Florida.
