Today at a local native nursery, I came across a version of Westringia (according to the nursery owners of course) called Peppermint Cream. EAch time I searched via Google images I came up with an image that was definitely the same as the plant, only it was being called Serissa on Google. Serissa is an asian species, seen commonly here in Australian gardens.

Please can you help with 100% i.d, which is the correct name??

Yes that's it, that is exactly what I saw. So this would lead me to think that the google hits were incorrectly calling it Serissa, have to say very alike in foliage appearance. Thank you!!
