@ ardesia is right, it will not creep over the edges and when it does it spreads to the surrounding areas. To keep it contained in your bed you have to hedge it. After a time when the plants mature the Asiatic Jasmine actually are hedged here and look like 12" little hedges. I have some wedelia/Trailing Daisy that is a fast grower, if not too fast! But it trails over the moss rock edges of the bed it's in and still keeps that trailing look with some simple pinching back. It dies back in the winter and comes back each year. It is covered in yellow daisy flowers all summer and fall.
