I am eternally irritated by gardeners not realising that Kniphofia is named after Herr Kniphof. Being German, his name is pronounced K nip hof. ( hof means a courtyard or formal area, and the K is pronounced) The plant is not named after a Greek, when ph would be pronounced f . Hence K nip hofia. It would still be bearable without the pronounced K, but there are NOT two f sounds. Please broadcast this to the linguistically challenged English speakers!
