flowers/plants grown with periwinkle

Question

I have a large area with this ground cover under some rose of sharon shrubs along with Annabelle hydrangea and hostas. I would like to add other flowering plants but I’m concerned the vinca will eventually choke out the flowers. Do you have any suggestions?

Answer 1

Hello,
Thank you for sending us your gardening question.

Yes, Periwinkle can become invasive and overtake plants.
From personal experience though I have not had an issue. I have Vinca vine planted along the back of a retaining wall where my perennial bed is.
Most of my perennials are larger scale and I do think this helps.
Here is a link with more information.
