This is one of two artichoke plants. The other is not quite as far along. I wasn't expecting to get any artichokes this year because I read that they must go through a winter before they will produce. I guess the cold snap earlier in the year fooled them into thinking that they had wintered over.
I think that this is a parasitic wasp sitting atop of a radish leaf. Parasitic wasps are good guys so I hope he hangs around.
