Growing Morning Glories From Seed Is Easy
Morning glories (Ipomoea) are amazing flowers that hummingbirds, bees, and butterflies adore. They are versatile and can be planted in a variety of ways in containers, on a trellis, in a hanging basket, or on a fence. They are also quite stunning to look at when they climb around a lamp post or a mailbox.
Growing a morning glory plant from seeds is incredibly easy, but if you want to get the best results, you need to prepare your seeds before they are planted. I use two ways to prepare them. The tough outer shell can be nicked with an emery board or nail file, or soaked overnight in water. Either way will work, as the purpose of the advanced preparation is to encourage and speed up germination. The step-by-step instructions are included below.
Morning glories are hardy in USDA growing zones 3–10. They have slender stems, heart-shaped leaves, and trumpet-shaped flowers of many colors, depending upon the variety you choose to plant. They are drought-tolerant and will bloom from early summer right up to the first frost.
Step-by-Step Seed Prep Instructions
Once you have your seeds ready, do the following:
- I like to get my morning glories started inside so I can watch over them like a mother hen. Plus, I prefer to start them off in those small peat pellets that expand when they are watered (see photos above). Just put 2–3 seeds that have been soaked overnight in each pod and cover them lightly with some peat moss. I buy the pots that are already in a long, horizontal container with a clear top, which becomes sort of a miniature greenhouse. They work great and I can't say enough about those tiny pods, which eliminate the "dirty hands" part of growing that many people hate.
- Water thoroughly in the beginning, then be sure to keep your pods moist during germination (but not soaking).
- Once you begin seeing some sprouts, you know they are rooting and you can move them into a larger pot. I use those 3" biodegradable pots that you will see in the photographs. That's where they will stay until it's time to transplant them outdoors soon after the last frost date. When the time is right, you can plant the whole thing in the ground.
- Be sure to plant your morning glories in soil that drains well where they will receive a lot of sunshine.
A Few Morning Glory Varieties of Note
Not exactly black, but a very deep, dark purple-black color.
They grow somewhat slower than most other morning glories.
White blooms striped in pink.
A vining annual that also works great as a groundcover.
Huge huge star-shaped blooms that are dark blue with a purple star and a white edge.
Cultivated by the Japanese to have a profusion of beautiful, 5" flowers.
Star of Yelta
These beauties have purple blooms, each bearing a bright pink star and tiny white central dot.
These remain open longer during the day than most other morning glories.
These have a deep, rich purple hue that makes the white star center really stand out.
Like all morning glories, these plants will climb anything in their path.
What Insects or Pests Are They Vulnerable to?
Morning glory plants can be vulnerable to attack from several insect pests, including the following:
- Aphids: These tiny, soft-bodied insects tend to feed in colonies and excrete sweet, sticky honeydew, which can attract ants to the plants and interfere with the plant's photosynthesis. Honeydew can also provide a breeding ground for sooty mold. Ants don't destroy morning glories but they protect aphids by keeping predatory (beneficial) insects away.
- Caterpillars: The larvae of some moth and butterfly species (caterpillars) will decimate morning glory plants by feeding on the leaves. The result is ugly holes or jagged leaf tears. Often, a plant is completely stripped of its leaves. Some caterpillars bore into the stems of the plants causing them to collapse.
- Spider mites: They are true spiders, with web-spinning abilities, and they live in colonies and attack morning glory plants on the underside of leaves sucking juices out of the foliage.

I agree completely, Peggy. I hope to have them growing all over our wall around our backyard this year. Thanks!

At our last home prior to planting shrubbery along our backyard fence, I grew morning glories. They self-seeded after the first year and were so beautiful when in bloom. It is an inexpensive way to embellish a fence.
