Oh, English ivy. That makes sense. I'd never seen it with the greenish white flowers (that look like berries from a distance). I see that it will get dark berries later?

It seems like it would harm the magnolia, right? I will pull it down if so.

The weight can be damaging, yes. Of more concern is the fact that it is now flowering and could still produce berries. Birds eat these and then spread the plant far and wide, which is one of the reasons English ivy is considered an invasive species in so many locations. Although I would not have considered that to be a major concern in a zone 5 location, that is likely how your vine started in the first place, unless you planted it intentionally.

It was around the house when I moved in in 1998. I was able to get rid of it in the front and side of the house and it didn't exist where it is now. If I had it before why didn't I recognize it? I'd never noticed the flowers/berries back then. I wasn't sure what this was because it just popped up. Maybe it came from my neighbor. I'll check where it's rooted. It's by my driveway so it doesn't get much attention.

I have to give it props for being able to grow where it is because I thought there wasn't an inch of uncovered ground.

I'll try to get much of it down before it turns to berries. I have a tall ladder. Also, if anything fell berry-wise the ground is covered (Boston ivy) so birds wouldn't see them.

There is a creeping juvenile stage that spreads over the ground and up supports, produces lobed leaves and does not flower. After a time growing up supports a transformation to the shrubby, flowering adult phase you are asking about here occurs.

Also the adult growth can start to emerge from ground level mats of juvenile growth at some point as well.

There’s a juvenile stem climbing the brick wall in the background. As far as I can tell your ivy has already flowered and those are not buds but early stage fruit.

I think the vine growing up my neighbor's brick wall is Boston Ivy. I will go outside and double check. My neighhbor and I have boston ivy growing on the ground. I don't mind it because it doesn't leap across the driveway to "volunteer is some new location. It's bounded by the driveway on my side but runs more freely on her side.

What I can see in the background on the brick wall is definitely Hedera helix. There’s some on both the left and the right. They may have Boston Ivy elsewhere but that’s not what’s in the photo.

Interesting. I went out and looked just now and all I see on her side both on the ground and her house is Boston Ivy. I can take a better picture when her blinds are closed :-) I don't doubt your ability to identify English vs Boston ivy at all. I'm just thinking the vine halfway down to the far right edge is too small to ID? On the other hand, there's an outside chance she pulled it down since I took the photo about a week ago. The ones I see today are all Boston ivy.

On the other matter I don't see any sign of the English ivy growing on my tree being rooted in her yard. It must be in mine under a thick, thick carpet of Boston ivy. It's true something could easily pop up between the B. ivy leaves if it could manage without any sun until it does. The occasional tree volunteer sprig does that until I pull them.

Being home for the pandemic has allowed me to concentrate on tidying up all my yards.

The two strands I can see adhering to the brick wall are Hedera helix. No question. It is quite distinctive and isn’t too small to id, especially when enlarged. Perhaps you could show us a picture of your ‘Boston Ivy’ and we can see if we are talking about the same plant? Boston Ivy, Parthenocissus tricuspidata, is deciduous so, if in a couple of weeks, your ‘Boston Ivy’ is still green, it’s not BI. BI is an unusual ground cover, whereas Hedera helix is very common. I wonder if this is a case of mistaken identity.
