According to Dave's Garden "no". http://davesgarden.com/guides/pf/go/107577/ sorry.
Got this from gardenweb.forum- I also suggest you have a look at this site under this subject because I get the feeling that they'll take over-they're were called a 'noxious weed'.

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/town...it doesn't look like this variety is on a quest to for global domination...at least not yet. ;-)
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.

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.
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.
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?

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.
Morning Glories can be planted in the garden from seed but you'll have much earlier blooms if you start them indoors 5 or 6 weeks ahead of planting.
The Morning Glory loves to face East as they bloom in the mornings and fade away come the hot afternoon sun. So don't plant morning glories facing the West. Although they fade away each day new ones will be there to open up in the morning.
Morning glories readily reseed themselves and keeping them all in one place is almost impossible.
The little black seeds fall all over the place once the little 'pods' on the vines dry up and open, so plant morning glories in an area by themselves so they have free reign to do what Mother Nature intended them to do. MULTIPLY!

I purchased two Heavenly blue Morning Glories and was wondering what the temperature needed to be so I can plant them outside? I live in New Jersey and we haven't had consistent temperatures yet. Anita
I have a perennial Morning Glory that has rooted and adapted to Ohio, but is from California. The trouble is it never blooms, or rarely. It is in full sun. It has big blue flowers, and I was wondering if a chemical that is put on Hydrangeas to make them blue would help?
Hardiness Zone: 4b

I live in southeastern Ohio. Is it too late to start morning glories outside? It is going to be in the 80s today. I'm not sure how the weather works up here (I'm from Florida), so I am slowing learning. I am having to dig out clay and replace it with compost. Should I start them in the shade or plant them in full sun, in the morning sun?
Thanks, have a great day.
