I was able to complete the refrain yesterday, by obtaining a Sage plant.
Parsley (flat-leaf variety) and thyme we have had for a while. I purchased a large Rosemary plant a few weeks ago from a fellow that sells from the front of Swansea Street Markets (greengrocers and fruiterers), and yesterday I got what I would consider a starter plant of Sage from Waldecks Nursery.
I haven’t planted the Sage yet, but I trimmed the Rosemary and made some stem and tip cuttings.
The side verge which goes along the side of the block, I want to plant a mixture of lavender and rosemary.
I have about ninety lavender plants, and it will take a little while to propagate a similar number of rosemary plants. But I’m finding the processing of “from little things grow” a lot of fun.
