They are so similar that it is hard to tell without a closeup of the inside of the flower. The foliage looks the same to me. Which ever it is, I like it. If it doesn't vine around things, it probably is the Barleria repens, or do they eventually vine and wrap as well?
Hi Brugie, you are so right, learning is an ongoing process! :-) I just happened to recognize it because I am growing it as a groundcover in my garden.
The two large green bracts at the base of the plant are diagnostic for Barleria repens. They are persistent and later turn brown as the seed pod develops, protected within. Size of course is another criteria, but this is often hard to tell from a picture.
Glory, it will benefit from a regular pruning back, or else it can get rather lanky.
