Passion flower vs Rhododendron

Question

My Passion flower is growing up through my Rhododendron plant, it seems to be taking
over – the rhododendron is healthy and about 7 foot tall – will the passion flower
do any harm to it?

Answer 1

Yes, it could become an issue for your vine to be growing in the Rhododendron.

It can smother the plant and it likely the Rhododendron will decline.

Moving the vine would be advised.
