i can't think of

The name of this plant. But maybe i will think of it while typing away.
It's not a native species, but it grows very easily in the Yukon, on certain location.
It is a beautiful climbing vine, but i find it hard to see it's beauty when you don't really look.
It likes growing in industrial areas on chain link fences. (You know the name right?)
For most of the year it has these grey puffs, from a distance it just looks like a grey mop sticking to the fence. I often wonder; now does it improve the look of the fence or not?
But really it's beautiful the yellow flowers quite striking when look at them from close by and look at its delicate bright green leaves.
This morning it was all sparkling, because of the melting frost and lifting fog
First when i woke up we are in a cloud.
The cloud dissipates.
this moment i took the photo
you see at the bottom of the photo the fog is rising out of the river, a half hour later
we are in the clouds again,
And then when that lifts,
A Bright Sunny Day! up to 16C and we sunbathing while soaking in the Takhini Hotsprings

Now what's the name of that vine?
