Eureka, California
"Eureka" received its name from a Greek word meaning "I have found it!" This exuberant statement of successful (or hopeful) gold rush miners is also the official motto of the State of California. Eureka is the only U.S. location to use the same seal as the state for its seal.
Urtica dioica
In the German language, the idiom "sich in die Nesseln setzen", or to sit in nettles, means to get into trouble.
In Hungarian, the idiom "csalánba nem üt a mennykő" (no lightning strikes the nettle) means bad things never happen to bad people. The same idiom exists in the Serbian language неће гром у коприве. In Dutch, a "netelige situatie" means a predicament. In French, the idiom "faut pas pousser mémé dans les orties" (don't push grandma in the nettles) means that we should be careful not to abuse a situation. The name urticaria for hives comes from the Latin name of nettle ("Urtica", from urere, to burn).
