Hi Yowie,

Since you don't know the specific cultivar, you should move these photos to the general Catharanthus roseus database page.
The thread "ID Petunia" in Plant ID forum

Vinca (Catharanthus roseus)

You can use the "" Move this image to another plant" in "Actions" or @zuzu can help you, if needed.

Thanks!

I've moved the images. Thank you, Danita.

Thank you, Zuzu!

Thanks both
