apple of Peru [2]

N. physalodes has many, branched, erect, dark coloured stems to 1.2m, with toothed, ovate green leaves to 10cm long, rather thin in texture, and solitary flowers borne on short stalks from the axils of the leaves. The flowers are pale blue-mauve with a white throat, 5-lobed, 2.5-4cm across, opening in the middle of the day. The calyces are tinged and veined with dark purple, expanding after flowering to encase the small brown fruits in ridged, papery globes
