Solved Plant ID, please!

Hi,

Could somebody please help me to ID this?
I bought a house in December, I removed most of the shrubs and bushes trying to start fresh, but this seems to benefit of the new conditions and it's spreading everywhere.
Somebody on another forum suggested that it could be Herbaceous Elderberry, what do you think?

 

Not sure but it looks a thug...
WELCOME TO GARDENERS CORNER.

 

I think it could be Rhus suckers.

 

It looks like a sucker from a nearby tree.

 

Thank you for the suggestions!

It is definitely not a sucker from a nearby tree, as there is nothing close enough.

The frustrating bit is that it spread to the middle of the lawn I just grown from seeds. So after more than a month of care, now my lawn is in pieces, as I started to dig the thing out.
I have no idea how could I fix that anytime soon.

 

So what is that big tangle of roots with it growing out of it?

 

When I bought the house, the garden looked like this:


In the spring I have removed most of shrubs and bushes, setting plant beds on the sides, some new bushes on the back and grass on the rest.

 

Looking at the mass of roots. I'd be inclind to say, Rhus. Staghorne Sumac, although the leaves in the first photo do look a bit glossy.

 

vadiro in your new image I can clearly see a very tall Rhus, back centre.
All the roots /suckers are coming from that.
You will need to follow each shoot and dig it all out right back to the parent tree..

 

Over the years I have often thought, 'Hey this fellow should be renamed, 'Wandering Jew'. No semetic abuse intended. Wandering Jew, Tradescantia tends to do as it's name implies, even if mainly grown as a pot or container plant.

Rhus is as it seems to be, something of a nomad. Years ago, my garden suddenly played host to a couple of trees. Where did they come from? Agreed they tended to give the garden a kind of tropical appearance, similar to sun shading graceful palms. Then without a bye your leave, theyed gone.
Come that time of year, my downstairs neighbour had a Rhus in her garden. It stayed only for a single season. It hen missed out next doors garden and a couple of seasons later sprung up in the garden three spaces away. Now today. It seems to have backtracked. Next door has a fast growing specimen sprung up between his decking booard.

I have to honestly admit. I have never undertaked a closeup study of a Rhus. What makes it to survive with this life style. It's flower cones obviously play a fruitful part in progeneration. Then also. The stems, branches etc are so flexible and covered in this velvety kind of coating, which contributes to it's nam. Staghorn. The animal, the stag, its antlers are also covered with this velvety coating. So In an attempt at finding out why etc.

Are the seeds the main entity of reproduction. Might it be the brittleness of the stem structure. I have actually carried out some basic reseach prior to my Plant Pathology status. The soil where the plant has survived can naturally contain fibrous root remains, but I have found nthing to suggest that this subject develops, sends out root runners. Something to look into.

 

We grew one.
Deliberately planted in grass where we hoped mowing it would keep it in check.
It seemed to be working...new sprouts got mown off.
Later it popped up in the middle of a flower bed...maybe 15ft from the parent tree.
I can vouch for them sending out long roots which in turn sprout leaves and if left alone will form a new shrub/tree.

 

The garden has been, from what I know, not maintained for years, but when we had the house views, sometimes in September, I have noticed no sprouts. They got out only in May, having removed the bush a couple of months back.
Anyway, the roots seem to go for about 12ft.

 

almost half the width of my back patio garden

 

At that point I gave up
