Symphytum officinale L.

Species description (© Flora Helvetica 2018)

40-120 cm hoch, ästig, zerstreut bis dicht abstehend rauhaarig. Blätter lanzettlich, lang zugespitzt, bis 25 cm lang, in den geflügelten Stiel verschmälert, Flügel am Stängel bis zum nächsten Blatt herablaufend. Krone gelbweiss, purpurn oder rotviolett, 1-2 cm lang, röhrenförmig, mit einer Einschnürung unter den 5 Zipfeln. Schlundschuppen schmal, kahl, so lang wie die Staubblätter oder wenig länger, nicht aus der Kronröhre ragend, nur der Griffel die Krone überragend.
