Might as well throw some 4 O'Clocks seeds & oxalis in here.

Unfortunately, the answer is ME!!! Idiot that I am. I had nine MG seeds which is now like kudzu.

Well, to be fair, where I grew up MGs weren't invasive. I've had luck pulling up seedlings, using preen and lots of mulch. You have until they flower to get them out before they reseed again.

I do leave the native MGs, as they don't take over every thing and are small and pretty. Plus I probably couldn't get rid of all of them if I tried.

We were told they were not invasive. HA!!!

We have Morning Glories coming up under/ around our dogwood bushes I let some of them grow up through the bushes so it gives our bushes some extra color thoughout the year.

So I really do not mind them too much. Now if our climate was warmer and longer I would not want them here...

FWIW, four o'clocks are fine here, & I rather like oxalis--it's low & flowers over most of the year--though both can be invasive.

But dammit, don't let them plant Bermuda grass on this webpage, or I'll quit!

I have one. I've kept it in check all these years. I think I'm finally ripping it out.

After warning my son to be careful when siting morning glories for their enduring nature, he planted Heavenly Blue in a small bed to the side of the driveway bordered by a concrete slab patio along with grapes. They've only reappeared there for the 5 years since, and maintained the blue, so seems the hardscape's coralled them.

Find moonflowers more rewarding, and they've - unfortunately - only managed to reseed here once. Or maybe they do & the bunnies eat the sprouts before I can find them? Deer sure loved the moonflowers, so grew them in pots on the porch. The lone seedling spread along the base of the stone porch & never finding a leg up, made its way stretching along the base for 20' only a foot high & wide. Never would have occurred to me to plant a moonflower for that use, but it certainly made a charming low edging to the wall, like jim's morning glory border.

My Georgetown Tea was covered in bind weed and wild morning glories. I keep an eye on it...but I blinked and they took over!

I do know that morning glories will survive and reseed in my zone, since my neighbor had the standard blue morning glories all around her vegetable patch every year. Unfortunately, what survives and grows rampantly here is the nasty white bindweed, which is enough incentive to take it easy on the morning glories until you can tell the difference. As the same neighbor aged, she had bindweed growing everywhere in her large backyard, and it would constantly weave into their grapes on our shared fence (the grapes were most welcome) as well as Virginia Creeper (another unkillable thug). The new neighbors that bought their house have been trying to pull it out all over the yard, and I had to tell them how hard they're going to be working at that over the next few years, but how grateful I was that they were trying.

I have visions of a garden newbie putting up trellises to support the white bindweed as an ornamental plant, since the white blooms are pretty persistent all summer and attractive for at least a nanosecond before they start looking like The White Death that Ate Cleveland.

Sympathies to all for which this plant is a ruthless thug

I do plant Moonflowers almost every year. I'm convinced that if there's a heaven, it will smell like Moonflowers. Also, I'm a bit of a Night Owl, so the timing is better for me...

If I dare to take a few days off from gardening, and just water, the MG take over the rose beds, and almost everything else. They are terribly invasive here.
