Plant Taxonomy for Morning Glory Flowers:
classifies the most popular morning glory flowers as Ipomoea tricolor
'Heavenly Blue'. The cultivar
name befits this vine of sky-blue flowers.
Morning glories are annual vines
. These climbers
accomplish their ascent by twining their way skyward.
There's a good chance that 'Heavenly Blue' is the flowering vine you immediately think of when you hear "morning glories." But other types -- in other colors -- do exist, including vines with purple flowers. Flowers last only a day. True to their name, the flowers open in the morning, then pucker up later in the day. Vine length averages about 10 feet, and morning glory leaves are heart-shaped. Vines may reseed.
Morning Glory -- Tropical Flower:
vines are indigenous
to tropical regions of the Americas. But these tropical flowers
have long graced summer landscapes in cooler areas. Morning glory is the first vine to which many children in North America are introduced.
Sun and Soil Requirements:
Grow morning glory flowers in full sun and in a well-drained soil. The vines tolerate poor soil.
Uses for Morning Glory:
Other Types of Ipomoea:
A number of useful vines, besides 'Heavenly Blue' morning glory flowers, bear the genus name, Ipomoea, including:
- Ipomoea alba: moonflower
- Ipomoea x multifida: cardinal climber
- Ipomoea batatas: sweet potato vine
No doubt, the chief selling point of 'Heavenly Blue' is the beauty of its prolific flowers. Bell-shaped, the flowers are a striking sky-blue with lighter centers.
Morning glory vines don't need much care. In fact, other than providing them with water, the main thing to remember is what not
to do: fertilizing with a high-nitrogen fertilizer will cause your plants to grow mostly leaves and produce few flowers. Nitrogen is the first number in the NPK
sequence on the label of a fertilizer bag.
Growing Morning Glory From Seed:
The one drawback to growing morning glory vines is that, for an annual, they take a long time to flower (not till August), unless you help them along a bit. You can encourage earlier blooming by starting morning glory plants inside from seed in peat pots filled with potting mix, then transplanting them outside after all danger of frost has past.
Sow the seeds indoors about 3 weeks prior to the estimated last frost date in your region. Here's how to start morning glory flowers from seed:
- Keep seeds damp for 24 hours before planting
- Lightly scar the surface of the seeds
- Plant seeds a bit less than 1/2 deep and cover with potting mix
- Keep potting mix damp and warm (at least 70 degrees Fahrenheit).
Caveat: Morning glory, famous or infamous for its hallucinogenic seeds, is considered a poisonous plant; keep children away from it.
