Shoo-fly / Nicandra physalodes

Shoo Fly, Shoofly or Shoo-fly, Peruvian Bluebell, even Apple of Peru ... take your pick, lol. It is native to Peru, and it is known elsewhere as an introduced species and sometimes a weed. It is also kept as an ornamental plant, as at the Reader Rock Garden, where this photo was taken on 10 September 2013. This plant is a member of the Nightshade family, Solanaceae. The green or black-mottled calyces have always fascinated me. Branches of the mature Chinese lantern-style fruits can be dried and used for winter decoration.
