Euonymous fortunei.

Do you know anything about the plant? Is it harming the tree or can I leave it alone? Thanks. Also, Google said the Euonymous fortunei is flowering, the vine have isn't flowering

Just because you haven't seen yours flowering doesn't mean that it can't or won't. It has the potential to do so. I don't live in your climate and it isn't a problem here so I suggest you research the plant in the light of where you live. It is invasive in some regions of the US. The id is correct.

It is an invasive, despite being a pretty vine. Even if it seems to stay "in control" in your space, I believe this is a plant that makes berries or seeds that other animals eat and 'drop' or 'deposit' elsewhere, causing it to propogate. We removed the barberry in our front yard foundation plantings when we moved in for the same reason. In fact, 8 years later, I am still finding risidual barberry volunteers trying to pop up! I'd suggest removing it and disposing of it not in your compost. Good luck!

Yup^.

I agree with Jill on all points except I would put this in my compost heap. It doesn't appear to have any fruit on it and the green leaves and stems will decompose. Just chop it up or chip it. It will rot down with the rest of the materials.

I missed that bit about not composting it. Agree with floral-there should be no issue.

Ah! so floral and tom, is it once something "bad" that goes to seed or berry stage that you shouldn't compost it? We pulled a whole bunch of wild lettuce that had the puffballs formed and that I threw into black garbage bags. And the there's the continua stiltgrass fight (mowing low now...)!!!

..............also, it does depend on the nature of your composting setup; So, if you really tend your pile, turning, making sure high temps are being reached, folding the pile's outside into the center periodically, then almost any organic material will break down and not go on to cause problems. But........if any one of these factors is not being met, such items can go on to cause problems. In my case, I've been composting forever. It's as natural a part of my yard as having a garbage can. But I don't really manage my pile. I just tunnel into the center when I need some good stuff, and while I do turn mine, it's not really often enough. Yet I've not had any issues. And I'm certain I've thrown such items into mine now and again.

Since we don't know where you live, research the comments about the euonymus being invasive. That is not the case everywhere. The invasive characteristics of most listed invasive species are highly dependent on location. With the euonymus, this tends to be centered in the eastern part of the country but even there, not uniformly.

Exactly, we still don't know where the OP is. See my post above.

"I don't live in your climate and it isn't a problem here so I suggest you research the plant in the light of where you live. It is invasive in some regions of the US"

I have never hated a plant as I hate this. My plant identifier app called it winter creeper, and in the year that I've owned this 0.12 acres, I've hauled 60 lawn and leaf bags of it away. We finally got the main stump out last month -it was tree sized and had a piece of rebar embedded in it. So, in z.6a, US, it's a menace.

Yes, Winter Creeper is a common name used in the US. I like to use botanical nomenclature to ensure that the plant under discussion is clearly identifiable to all readers everywhere.
