Annual Biennial
A hardy annual with many, branched, erect, dark indigo blue to black stems to 1.2m and toothed, ovate green leaves to 10cm long, rather thin in texture. Short stalks produce short-lived, solitary pale blue flowers with a white throat, opening in the middle of the day from June to October. Round, green-brown fruits are encased in green or black calcyes, similar to Chinese Lanterns, and can be dried for winter decorations
