Crimson Glory

Will these grow nicely up old conifers?

Hi Jean, what plant are you asking about? Is it an ivy, I don't know one called Crimson Glory.

I have heard Vitus cognetiae called crimson glory but maybe other things are as well

If It's an ivy it will climb and smother anything it gets near eventually. Vitis c would need better soil to do well, but if it does well it's massive.  Are the conifers dead or just old?

Is it this ?
