A report from Berlin, the former headquarters of Urban Plant Research. While I’ve been busy getting oriented amongst the tropical flora of Hawaii, my friend Dorothee of Lilienfeld sent in this report from the grounds of Schloss Charlottenburg. She found the station of Queen Luise thus decorated. She notes that the pearl earrings are made of snowberries. These are also known as “Knallerbsen,” the German term for the small novelty explosives now in English as bang-snaps or poppers. Was it the Queen’s birthday? Or did the fall abundance of horse chestnuts and berries inspire an impromptu decorating session? I don’t know, but I am charmed.
