Evolvulus pilosus
This is a popular species for landscaping because of its toughness. It's used as a low shrubby specimen or groundcover. The main feature is the blue flowers (there is also a white-flowered form), so like most flowering species it isn't suitable for constant clipping. However, it needs to be cut well back from time to time to keep it fresh and compact and looking good.
More information about Evolvulus coming to this page in the future.
