What Are Morning Glories?

Morning glory is a common name rather than the name of a single species. In this section, you will explore the origins and domestication of morning glories as well as their cultural significance.

Origins and Botanical Background

Morning glory is a common name rather than the name of a single species. Many familiar ornamental morning glories belong to the genus Ipomoea in the bindweed family (Convolvulaceae).

Their native ranges vary by species. Common morning glory (Ipomoea purpurea) is native to tropical and subtropical parts of the Americas, while Ipomoea tricolor is native to Mexico. Moonflower (Ipomoea alba) has a broader native range across tropical and subtropical America.

Through cultivation and selection, gardeners have developed numerous ornamental cultivars distinguished by flower color, pattern, size, and growth characteristics.

Types of Morning Glory Flowers

Morning glories offer an impressive range of flower colors and patterns, from clear sky blue and deep purple to white, red, and striped combinations. Although many are commonly grouped together as morning glories, individual cultivars may belong to different Ipomoea species.

Here are six distinctive morning glories to consider for the garden.

1. ‘Heavenly Blue’ — Ipomoea tricolor

‘Heavenly Blue’ is one of the best-known morning glory cultivars, producing large, trumpet-shaped flowers in a striking azure or sky blue. The blooms have contrasting pale centers that draw attention to their funnel-shaped throats.

The vigorous twining vines grow quickly when provided with warmth, sunlight, and vertical support.

Flower color: Sky blue with a pale or white throat
Growth habit: Fast-growing twining vine
Bloom period: Summer into early fall
Best use: Trellises, arbors, pergolas, and fences

2. ‘Flying Saucers’ — Ipomoea tricolor

‘Flying Saucers’ stands out for its unusually patterned flowers. Rather than producing a single solid color, its trumpet-shaped blooms combine white with irregular blue stripes and markings.

Because the pattern can vary among individual flowers, the vine can produce an especially eye-catching display when grown vertically.

Flower color: White with blue stripes or markings
Growth habit: Vigorous twining vine
Bloom period: Summer into fall
Best use: Trellises, fences, arbors, and other vertical supports

3. ‘Pearly Gates’ — Ipomoea tricolor

‘Pearly Gates’ offers a softer alternative to the brightly colored morning glories. Its luminous white, trumpet-shaped flowers stand out particularly well against the vine’s green foliage.

Like other Ipomoea tricolor selections, it grows as a vigorous climber and benefits from sturdy support.

Flower color: White
Growth habit: Twining climbing vine
Bloom period: Summer into fall
Best use: Trellises, arbors, fences, and light-colored garden displays

4. ‘Grandpa Ott’ — Ipomoea purpurea

‘Grandpa Ott’ is an heirloom morning glory prized for its richly colored flowers. The trumpet-shaped blooms are deep purple with a reddish-purple star extending from the center and a contrasting pale throat.

Its dark flowers make it especially useful for adding deeper color to fences, trellises, and mixed vertical plantings.

Flower color: Deep purple with a reddish star and pale throat
Growth habit: Twining vine
Bloom period: Midsummer into fall
Best use: Fences, trellises, arbors, and cottage gardens

5. ‘Scarlet O’Hara’ — Morning Glory Cultivar

‘Scarlet O’Hara’ provides a warmer color than the familiar blue and purple morning glories. Its trumpet-shaped flowers are rich reddish-pink to crimson, creating a vivid display against the green foliage.

Like other vigorous morning glories, it performs well when trained onto a vertical structure where the vines have room to climb.

Flower color: Reddish-pink to crimson
Growth habit: Twining climbing vine
Bloom period: Summer into fall
Best use: Trellises, fences, arbors, and colorful vertical displays

6. Moonflower — Ipomoea alba

Moonflower differs from familiar morning-opening varieties because its large white flowers unfold in the evening. The fragrant blooms remain open through the night before eventually closing, making this species particularly interesting for evening gardens.

Ipomoea alba is a vigorous tropical vine that is often grown as an annual in colder climates. Its large flowers can reach about 6 inches across, making them considerably larger than those of many familiar morning glory cultivars.

Flower color: White
Growth habit: Vigorous twining vine
Bloom period: Midsummer into fall
Best use: Evening gardens, fences, arbors, trellises, and areas near patios or seating

Can Morning Glories Become Invasive?

Some morning glory species can self-seed readily and may spread beyond their intended growing area. Their behavior varies by species and location, so gardeners should check local invasive-plant recommendations before planting.

To limit unwanted seedlings, remove spent flowers before mature seed capsules develop and dispose of unwanted vines responsibly.

Are Morning Glories Toxic?

Some morning glory species contain compounds that can cause adverse effects if ingested. Seeds are a particular concern with certain species, including Ipomoea tricolor.

Keep seeds and other plant material away from children and pets, and avoid consuming any part of a morning glory unless the species has been positively identified and its safety is established by a reliable source.

How to Grow Morning Glories

Morning glories are vigorous climbing plants that generally perform best with plenty of sunlight, well-drained soil, and a sturdy structure to climb. Exact requirements can vary somewhat by species and cultivar.

Planting Morning Glory Seeds

When to sow: Plant outdoors after the danger of frost has passed and the soil has begun to warm.
Choose the location: Select a sunny site near a trellis, fence, arbor, or other suitable support.
Prepare the seeds: Some morning glory seeds have hard seed coats. For Ipomoea tricolor, nicking the seed coat and soaking the seeds overnight before planting can help prepare them for germination. Follow species-specific recommendations when growing other morning glories.
Sow shallowly: Follow the recommended planting depth for the species or cultivar you are growing.
Guide young vines: As seedlings develop, gently direct the vines toward their support if necessary.

Light and Soil

Light: Provide full sun for strong growth and abundant flowering.
Soil: Use well-drained soil that does not remain constantly wet.
Fertility: Avoid excessively rich soil or heavy fertilization, which can encourage leafy growth at the expense of flowers.

Watering

Seeds and seedlings: Keep the soil moderately moist while seeds germinate and young plants become established.
Established vines: Water when the soil begins to dry rather than keeping it continuously wet.
Containers: Check container-grown plants more frequently because potting mixes can dry faster than garden soil.

Growth and Support

Growth: Morning glories grow vigorously during warm weather, and many can produce several feet of growth in a single season.
Support: Provide a trellis, fence, arbor, pergola, or similar structure for the twining stems.
Training: Gently guide young vines toward their support. Once established, they will usually continue climbing on their own.
Spacing: Give vines enough room for air circulation and avoid allowing vigorous growth to overwhelm nearby plants.

Fertilizing

Feeding: Morning glories generally do not require heavy fertilization when grown in reasonably fertile soil.
Avoid excess nitrogen: Too much nitrogen can encourage vigorous foliage while reducing flowering.
Before fertilizing: If growth is poor, consider soil conditions and possible nutrient deficiencies rather than automatically applying fertilizer.

Pruning and Maintenance

Pruning: Remove damaged, diseased, or unwanted growth as needed.
Training: Redirect vines that begin growing outside their intended area.
Seed control: Remove developing seed capsules before they mature if you want to limit self-seeding.
Local concerns: Because some morning glory species can spread readily, check local invasive-plant recommendations before planting.

Landscaping With Morning Glories

Morning glories are particularly useful where fast-growing vines and vertical coverage are wanted during the growing season.

Trellises and arbors: Train vines upward to create a flowering vertical accent.
Fences: Use vigorous varieties to soften plain fencing or add seasonal color.
Cottage gardens: Combine morning glories with annuals and perennials for an informal planting style.
Evening gardens: Grow Ipomoea alba near patios or seating areas where its fragrant, night-opening flowers can be appreciated.
Color combinations: Blue and purple morning glories can contrast effectively with yellow, orange, or pale-colored flowers.
Pollinator gardens: Flowering vines can provide nectar resources for visiting pollinators; attraction varies by species.

Pest and Disease Management

As with any plant, morning glories can be susceptible to pests and diseases. Here are some tips for managing common issues that may arise.

Common Pests

Morning glories may occasionally be affected by pests such as aphids, spider mites, leaf miners, and caterpillars. Inspect leaves and stems regularly so problems can be addressed before infestations become severe.

Aphids: Look for clusters of small insects on tender stems, buds, and leaves.
Spider mites: Watch for stippling, yellowing, or fine webbing, particularly during hot, dry conditions.
Leaf miners: Look for winding or blotchy trails inside affected leaves.
Caterpillars: Check damaged foliage for chewing insects or feeding damage.

For minor infestations, remove badly affected foliage or dislodge pests with a strong stream of water. If additional treatment is necessary, choose a product labeled for the pest and plant, and follow all label directions.

Disease Prevention

Morning glories can be affected by fungal diseases such as powdery mildew and leaf spot. These diseases can cause discoloration and distortion of the leaves, and can eventually lead to leaf drop.

To reduce disease problems, provide good air circulation around your morning glories by spacing them out properly and removing any dead or diseased plant material. You can also water at the base of the plant rather than overhead to avoid getting the leaves wet. If disease develops, remove badly affected plant material and confirm the cause before treating. If additional control is necessary, choose a product labeled for the specific disease and plant and follow all label directions.

By following these tips, you can help keep your morning glories healthy and beautiful all season long!

Final Sprouts of Wisdom

Morning glories offer an impressive range of flower colors and patterns while quickly adding vertical interest to fences, trellises, and arbors. Choosing the right species or cultivar is important because growth habit, flower size, bloom time, and climate tolerance can vary.

Give these vigorous vines plenty of sunlight, well-drained soil, and sturdy support as they grow. In areas where morning glories spread readily, removing seed pods before they mature can also help keep volunteer seedlings under control.

Whether you prefer the brilliant blue flowers of ‘Heavenly Blue,’ the richly colored blooms of ‘Grandpa Ott,’ or the fragrant nighttime flowers of Ipomoea alba, morning glories can bring colorful climbing growth to the summer garden.
