Pinch some off and smell it.
Huh. There is in South Africa. So what does it smell like?
No smell at all. But it turns a nice reddish brown as fall arrives.
if this is growing in a moist acid environment it may be bog rosemary (andromeda polifolia), a native sub shrub that is often found in peat bogs or swamps. It is not related to rosemary though.
