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
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.
Caveat: Morning glory, famous or infamous for its hallucinogenic seeds, is considered a poisonous plant; keep children away from it.
Growing Morning Glory From Seed:
The one drawback to growing morning glory vines is that, for an annual, they can take a long time to flower in some circumstances (mine typically don't bloom 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).
Note: Not everyone has so much trouble getting their morning glory flowers to bloom at a reasonably early time in the summer. Reader, Janet wrote to me in early July one year to observe:
"I live in Rhode Island and all my morning glories are now in bloom, both ones that volunteered from last year and ones that I did start indoors. However, the volunteers were in bloom before the ones started indoors by a good 2 weeks. My morning glories get southern and western exposure. I have heavenly blue, flying saucers, and Grampa Otts."
