That's really beautiful TJ, and still much tidier than mine.
The only herbs I get to grow successfully are mint, oregano, marjoram and chives. I have some Winter Jasmine but it only just barely manages to hang on and has never really done anything interesting. I keep meaning to move it somewhere else where it might do better. It's abviously fairly tough or else it would have been killed off by our winters.
I do have a veg plot but I didn't photograph that as at this time of year it's just bare dug over soil.

Number 3 looks interesting.
I had a really bad infestation of crane flies here one year when the grass was in good condition but ever since the moss has taken over I hardly ever see them. Maybe I should just be happy with the moss. After all it is greenish most of the year
