The companionway steps are visible and usable again after I cut back stuff that was growing onto and over them. Ferns, bugle, and mosses will grow back during the rest of the year.
I think this is Cape Thread-moss/Orthodontium lineare. It is growing on an old fence post in the top west corner of the garden. There is quite a bit more of it than there was when I first found it in November 2014. It’s one of my favourites.
