Catnip from the garden, I'm thinking of selling some, the rest I'm going to stuff in Xmas presents for the cats.
Tansy, I've not much used it but I'm always interested in adding to my herbal knowledge.
Here is my rather epically large Wormwood that I made the thrice infused Wormwood oil with. It just grows and grows no matter how much you prune it. I am so hoping Mugwort does the same!
