Morning glories are well known and popular; they need little description. I plant them every year along a wooden banister. Their brightly colored faces greet me in the morning as I go to work. By summer’s end, they have become close friends with the other plants, clasping their thin tendrils around the branches of neighboring shrubs and perennials.
Growing morning glories from seed is easy if you bypass that hard seed coat. Either soak the seeds in water overnight before planting or nick the seed coat with a file to allow water to permeate. I start my seeds by soaking in water and then planting in a small plastic cup with soil, under lights in my house. I start in late April and transplant after last frost, typically after Mother’s Day here in Virginia. Morning glory seeds can be direct sown but I do not have luck with that. They do need support so make sure they are planted in a place where the tendrils can clasp on to something.
Each year, I try different varieties and this year it was Heavenly Blue from Southern Exposure Seed Exchange. Heavenly Blue is an heirloom with bright blue flowers and a white throat. Other varieties have pink, white, magenta, or purple flower colors. I have even grown morning glories with variegated green and white foliage.
Morning glories have to be grown in full sun in order for the flowers to open up in the morning. They prefer well-drained soil, not too rich or one gets more foliage than flowers.
Even though I associate morning glories with summer they can often start blooming later in the season. Some people call them “back to school” vines because they seem to start (finally!) blooming in the fall.
