Bobby Tops

Realy? Wikipedia told me:
"The common names Policeman's Helmet, Bobby Tops, Copper Tops, and Gnome's Hatstand all originate from the flowers being decidedly hat-shaped" - nice names :-) ... here it is called "Springkraut - bursting herbs"
The ripe seeds "explode" when you touch them.

I have to admit that the wasp photobombed my blip. Hehe, thanks!
