The Lilium Martagon (Turk’s Cap Lily, Lily of Istanbul, Sultan Lily or Dragon Lily.) grows up to 2 meters and is one of the most beautiful lily flower in my area. I can find it mostly around 1000-1200 m in the nearby Alps, e.g. on the Rigi mountain range.
They exist in different colors, mostly they are in purple color:
Happy Liliuming 🙂
