Morning Glory Grandpa Otts :Question for Zone 4

Minneapolis, MN(Zone 4a)

I read the MG is very invasive down south but I hear that it does not survive our winters and won't reseed in Zone4a. I want to find out the experience of Zone 4 gardeners in this regard.

I want to take one Grandpa Ott plant and put it in my front yard and get it to wrap around a tree. Will it reseed next year? and will it be a tangled mess when it freezes over? i.e. will it be an eyesore when it dies. It will be shaded by the tree. So I don't know if it will grow that tall too.

maybe - best to save seed and replant

and will it be a tangled mess when it freezes over? i.e. will it be an eyesore when it dies.

it won't survive a freeze

Ipomoea needs full sun

A Clematis may be a better choice

Hi MN. I actually have a Grandpa Ott on my trellis every year. It's in part shade, and still blooms beautifully. It also reseeds faithfully, but not invasively. I get maybe a dozen plants come up, and just pull the extras. The first frost will wipe it out, then you want to tear it all out, but shake the seeds out on the ground. I contemplated having one grow up a tree trunk, but the tendrils will need something thin to wrap around, otherwise it'll just scrabble around on the ground.

Thanks. I feel more confident about planting it now. Hearing the reports of Southern gardeners made me worry if it would take over my garden.

I have Grandpa Otts that reseed here, but not heavily. They are growing on a chain link fence along with a Clematis. By the time the Clematis stops blooming, the Grandpa Otts starts, and keeps blooming until we get a freeze. They are in no way out of control, I seem to get 3 to 4 plants each year, this has been going on for at least 5 years, and I'm not over run with morning glories at all. They are in mostly shade and both do pretty well, they may do better in full sun, but I am thrilled with the look I get. They are both full, and flower profusely.
