Name of the heart-leaf climber?

This plant sprouted in one of my beds. Does anyone recognize it?

 

Looks very similar to the vine (2nd photo) in the thread Need help to identify a perennial and nasty vine | UBC Botanical Garden Forums.

 

I think this one is a climbing weedy annual knotweed. These are common here. If left it will later have little knotweed flowers instead of morning glory trumpets.

 

Scary- I'll remove it promptly before it takes my first-born!!!!!

 

Ron, is it as invasive as the Moring Glory mentioned in the other thread?

 

It's an annual, so all you have to do it pull it out and you are rid of that particular individual. It does not make an overwintering, invasive perennial root like the giant morning glory (Calystegia) that is locally notorious. If there is a reserve of climbing knotweed seeds present on a site then new seedlings will continue to pop up. It seems to like disturbed soils, such as in vegetable gardens.

 

Thanks again!!!!

 

It sorta looks like the "wild" Morning glory type plant that pops up around here. The flowers are slightly smaller than the more common types you get from purchased seeds. I usually only see it in a pale, pale lilac/purple, almost white.

I could be incorrect, but that's my gut feeling about it.
