First one looks like curly kale to me.
Second looks like a weed, and third looks like an anti-salad-theft device.

LOL - you made me check what I had posted then! I have a row of curly
kale in the same bed. It is not that.
The second in the gallery is Alliaria petiolata, or garlic mustard. It
took me a while to find that too.

The third was for the Vectra owners group, when I was seeking help with
the car alarm triggering spuriously. Made me very popular with the
neighbours when it happened during the night!
