Hello,
I love this plant I inherited it when I moved in & can say it grows like mad, covers everything & is very pretty.I would agree with others that it needs very little maintenance. I didn't know what it was last year so did nothing to it. It hasn't even started growing yet but covers my shed & trellis already. It's done exactly what I needed, a big screen.
I will have to cut it back this year after flowering as it will take over the house!
Took this picture this evening.
