    Seems like a good question to ask the seller. The only 2 vining plants that are commonly called hummingbird vine is the one you describe, and Campsis or "trumpet creeper". Campsis, unfortunately, doesn't have leaves like alcea. Hope you can find out.

    It is always faster to take softwood cuttings, but in this case it won't matter. This plant is highly invasive in most areas. They will root with no hormone most of the time, although hormone will increase success rate while decreasing chance of infection. Take a full fine cutting of about 6 inches to a foot, or roughly 1/3 of a meter or less.

    P.s. Don't fertilize trumpet vine. That will encourage leafy growth instead of blooms.

    It needs some direct sunlight to bloom. It will have leafy growth in shade. If it is an old plant, try cutting half the stems to the ground this fall or winter. That may re-invigorate it.

    It would not be wise to let that grow. That is Campsis radicans. This is a very invasive plant that will completely destroy foundation, sensitive plants and trees, and completely engulf structures. They also attract thousands of ants.

    I would recommend getting rid of it manually, and then pouring boiling water over the area for a week. Make sure to kill any instances that crop up further away too, since the roots will send up new shoots far from the original stump.

    I'm sorry that you have been plagued by this plant, and I hope that you can get rid of it before it destroys everything. This plant will laugh off harsh chemicals as if it were being watered, so get ready for a battle. Boiling water will kill just about anything with enough persistence.

    Indian Summer campsis needs little care. Plant in full sun in well drained soil. The vines grow rapidly, sometimes reaching 30 to 40 feet in one summer.
    Try pruning your vines to encourage more leaf and stem production. Also, the underperforming vine could be moved closer to the other one.
