This plant is about 20 years old. As it grew, I kept twisting it around the support frame. In the summer I would take it onto the patio, stretch out the branches, tying them to supports and love the happy blooming plant.
My son-in-law didn't appreciate it like I did & cut back all of the vining branches when he reported it a year ago.
Now I think it is an ugly shape. I can not spread its branches n the summer, but my Granddaughter cherishes this plant so I don't know what to do to improve it's appearance.
I tried rooting cuttings with no luck.
Please give me suggestions about what to do with this monster plant that doesn't like growing this way.

Ah, family - the perfect place to learn how to love!
What if you tried preparing a nice, tall, hoop-shaped trellis for it to grow along? It seems to have two main branches coming out left and right. Working with thick, white wire would make it look nice. And I read here : https://www.nature-and-garden.... that it can cope with pruning very well (now is the season for that). Start with a new pot, build the sturdy lattice into it, and then repot the whole thing shaping the plant and pruning off what doesn't fit, I guess.

Thank you, I have been ready to give up on it completely! However, it is a valuable family plant because the first day it bloomed was 18 years ago when my Granddaughter was baptized!

No need to repot it again. Unless you want a bigger pot.

I'd wait until it finishes blooming, then attack it with pruning shears, to the shape I want.

You mentioned rooting a new plant.
Thats, easy as apple pie. 👍😀
Un-ferall a branch that will reach to a pot next to mother plant. Leave attached to mother plant.
Below growing tip of branch just nick the branch a bit, part way. You want to be able to bury nicked branch about 2 inches in soil. Keep pot watered. Branch will make roots at nick in a few months. Then you can cut it off from mother plant.

It, don't get easier than that !
You can even do it in same pot, with mother. 👍👍
Ta. Ta. 😀

I understand your attachment to it, I also have plants that are decades old simply because someone I cherish gave it to me or even just commented something lovely about it... Great advice from Philipwonel about layering, that's an option, I hadn't thought of it! Good luck then with this one!

Philipwonel, Great plan for how to start a new one! I have lots of experience, but it seems like I still learn at least one new thing everyday!
