Botany picture #154: Rehmannia angulata

Rehmannia angulata (apparently now Orobanchaceae?), Botanic Garden of Zurich, 2009. This is a herbaceous annual species. Despite the fact that it has to be newly raised from seed every year, it is very popular in European botanic gardens. No wonder why - the flowers are unusually large and pretty.
