When we've been to Villandry castle in the Loire valley in 2013, famous for its decorative vegetable gardens, there was a fascinating exhbition: vegetables or parts of them made from porcelain as artwork.
From left to right: the first I'm not really sure about, savoy, Chinese cabbage and white cabbage. They look so real you want to bite into them, and I would have so loved getting one of these had they not been so horribly expensive.
Have a detail:
Yes, some of them had small beetles or the odd snail.
Again I'm not sure about the first (I think some kind of kale) and also about the last, but 2 and 3 are variations of mangold/chard.
