Is this a tree of some sort?

I've recently been weeding my herb garden when I noticed this plant growing. So I pulled it out along with its roots. But it turns out that the roots grew from some sort of "bulb" or a "core". I wasn't sure what it was so I planted it back.

 

A young elderberry ,Sambucus ?

 

Ailanthus as for me.

 

Well I doubt its a sambucus...cuz I live in Canada. It might be a Ailanthus? Can anyone confirm this. Im not any good with identifying plants

 

Rub the leaf, Ailanthus has unpleasant smell, strong enough to note it.

 

If you have a close look at one of the leaves, if it is Ailanthus altissima , common name Tree of Heaven, it will have a small pimple thing on the edge. This is a gland. Hope this helps. See.....

 

Is there any neighbouring shrub or tree from which it could be a sucker ? Interesting, the gland Luddite.

 

Alternate leaves, so not Sambucus.

Finely serrated leaf margin, downy leaf stem, and no gland, so not Ailanthus.

My best guess is a seedling Black Walnut Juglans nigra, but don't want to rule out a sumac Rhus as a possibility.

 

Thanks Michael, was wondering about sumac as a possibility, maybe suckering from a neighbours plant. Decaisnea sp. comes to mind , but maybe not enough leaflets.

 

It sure looks like a Wisteria to me.

I thought the leaves looked to be opposite.....?

 

Hermit, The leaf is considered pinnate, so alternates on this plant, i should have paid attention to this. The leaflets are opposite. Here is a better explanation http://en.wikipedia.org/wiki/Lanceolate. All interesting.

 

Thank you so much. Your comment and the link cleared up an area of confusion for me --- as I stumble along.

 

By the way, Sambucus do "live" in Canada (native species, garden varieties).

 

Yes but I doubt its in my region. So what do you think would be the closest resemblance.
I know its not Ailanthus, Hmm well there are no neighbours that actually have trees... But on the other side is a warehouse where wild plants and trees grow. I dont know really. I don't know if I should pull it out or not. Wait... O it might as well be a black walnut. Cuz you the the "bulb" I was talking about has the weird shape of an peach pit or maybe even an walnut

 

Err hum!...it's Wisteria sinensis of some variety.

Probably a sucker from below the graft, if it came from a neighbours garden. It will probably be a very vigorous vine, but may not flower at all, or very freely if this is the case.

Are you sure about it??? Cuz the plant is seems to have grown from some sort of "bulb". Its not from a neighbours garden or at least I dont think so because I can uproot it easily. Is there anyway I can confirm this?

 

Sure? Well - in my mind yes.
I ripped a piece off my Wisteria & stuck in the ground....

Not worth arguing about. let the little blighter grow & report back.

Not Wisteria, that has leaves with a wavy margin, but not a serrated margin.
