Planting Morning Glory:

Morning glories are easy to start from seed.

  • Soak seeds for 24 hours or nick the hulls prior to planting to speed germination, then sow them 1/2" deep directly outdoors.

  • In climates with long, cool springs, start seeds in peat pots indoors several weeks before your last frost date and move them into the garden when overnight temperatures stay above 45º F.

  • Vines will reach 10 feet or more within two months.

    Interesting Facts:

    Morning glories are native to the tropics. Flowers last for one day and are normally open only from dawn to mid morning, but may last all day under cloudy skies. Hummingbirds are attracted to the blooms.

    Although when mentioning that I grow Morning Glories, many think it's a weed , not so. I love to have them hang over my railing on the deck, some have also come up on their own and are a dark purple.

    I use Coke bottles, the small regular ones, to start morning glories. When the vine gets too long, I cut it off and put it in a Coke bottle with the top cut off.


    I then put a string through either end and attach it to a clothes line with a paper clip or twine.

    My balcony garden is a sanctuary for me to relax in. I had these beautiful purple and red morning glories winding in and around the panels of the balcony to make it more secluded. In Stratford, Ontario, Canada

    They grow tons of darling vines!

    I have seeds from mine that come up every year from the seed pods they leave on the vines at the end of growing season. I usually keep these and replant them. But as for the naturally sowed ones, they come up about the first of June maybe sometime in May. Morning Glories are my favorite, and that is good, because my Mom loves them too and that is why I have covered the fence with them.


    I am going to buy more seed this year and sprinkle it out along the growing area. They are great, to bring in and put in a glass of water... they are so fun!

    I'm moving to a condo with an east (and a little bit south) facing balcony. I'm thinking of planting morning glory and moonflowers in pots. Will a mainly east exposure provide enough sun?

    I have found east sun better than west sun since I live in Texas. Mine are growing on the east side of my nicely and even have trees blocking alot of the east sun.


    They are getting about 3.5 hours of direct sunlight each day and are blooming!

    I had pink morning glories last year although the package said they were blue. So this year I prevented any from reseeding and bought three or four more packages of heavenly blue morning glories.

    But, they are blooming pink. Is there something I can do to the soil to change the color? It's driving me bananas. I love the blue color. Please help!

    Flower color is genetic; only genetic modification will change the color.

    Try putting iron or aluminum sulfate on the soil... it works for Hydrangeas by changing the Ph. of the soil.

    I have 2 places where I want to plant morning glories. One is at the foot of my mail box post. The other is in the ditch in front of my house (water does not flow through it due to past neighborhood kids tossing basketballs, etc. in there and now it's plugged up which suits me great).

    My question is, how do I keep them from spreading? (Been there done that. OMG!) At the mailbox would be easy because I can plant them in a pot and only plant one or two on either side. But I can't figure out how to plant them in the ditch without them spreading all over the lawn.

    You actually can't stop them from reseeding but it is simple to pull up the ones you don't want as soon as they sprout.
    Also you can cut down on the seeds by pulling up the plant when they start to produce a lot of pods. They are usually looking kinda ragged by that time anyway.

    If you plant the kind that grow from seeds, just pull up the seedlings that start where you don't want them. If you plant the seedless kind, forget about keeping them from spreading. Can't be done. Wish I hadn't planted that kind several years ago.


    The photo shows the front half of our 12' x 60' mobile home and the hedge next to it. There are even more this year, in spite of having a whole truckload cut down and taken away each October.

    Hunner - when you search for something like that and are getting a lot of sites coming up in other languages, try putting in what you are searching for and then add an English word related to your search. I use GOOGLE for all my searches and when I looked up 'Convolvulus cantabrica' I also got a lot of stuff in other languages. I redid the search with 'Convolvulus cantabrica' and added 'perennial' that way it took out all the pages I couldn't understand.
    I found a few places that said it is hardy to zone 7-8, from southern Europe, a smaller plant 6-16" with "dainty" 1/2 - 1" blossoms, and "very nice in a rock garden". From the looks of it, you shouldn't have a problem with it taking over your yard/neighborhood/ doesn't look like this variety is on a quest to for global least not yet. ;-)

    I currently have morning glories in containers trailing up trellis. The foliage is beautiful, but here are no blooms. Come to find out they don't require fertilization, thus the reason why there may be no blooms.

    My question is can I replace the soil in my planters and eventually get blooms this year?

    When are we suppose to plant the morning glories? Do I transplant as soon as I see them coming up in the peat moss pots or after they are bigger?

    By Rosa Marie

    You should probably transplant them in the fall when they have grown some more and are sturdier. They are a perennial, so you want to be sure they are strong enough to transplant.

    I live in Phoenix, Arizona; when is the best time to plant morning glories? What type of soil do they need? I have grown them before in another state with no problems, but coming to Arizona, it's a whole new situation. Please help me. If I have to grow them inside, I will. I will try anything. I know I have to let the heat pass, (common sense). I just need someone to help me. Thank you.

    I tossed Morning Glory seeds all around the dog kennel in hopes it would provide a nice shade cover for summer, and it sure did. It looked nice too.
