Rosemary has lumps
I have a small rosemary plant, but half of it died back during the summer, so I pruned back the dead bits and it seems to still be alive. Apart from that there are some small brown lumps coming out of the stalks. Don't know if this is normal, as it looks like the lumps are breaking through the stalks.

If they do wipe away, then it might be scale. This article will help you with this problem.
