When I was growing up, we called these “periwinkles”. They now are called Vinca minor which is described as a trailing, viny sub-shrub, spreading along the ground and rooting along the stems to form large clonal colonies and occasionally scrambling up to 40 cm high but never twining or climbing.
We have them growing in mass pretty much contained in a bed on the west side of our house. While they don’t climb, I would argue that they do twine together. I digress, it is their simple beauty and upkeep that keeps them from being done away with. I just think the star in the center is a way nice bonus.
