The shoo-fly plant (Nicandra physalodes) can be grown from seed as a decorative addition to the garden. However, it can pop unexpectedly, particularly around bird feeders because it can be found in commercial bird-seed mixtures.

What it is the shoo-fly plant? Back to top

The shoo-fly plant is an annual that is sometimes grown from seed to add interest to borders. However, as occassional seedlings may appear in the garden (such as from bird-sown seed or seed fallen from a bird feeder), it is sometimes thought of as a weed.

  • It is a member of the Solanaceae or potato family
  • The plants and fruits are not considered to be edible, although there are no reports that they are harmful
  • A native to South America
  • Can be found on bare, waste and cultivated ground

Appearance Back to top

The shoo-fly plant is fairly distinctive;

  • The shoo-fly plant has bell-shaped flowers that are most commonly pale blue and white, but there are also forms with violet flowers and with white flowers
  • The flowers are short-lived, opening for only a few hours each day
  • Flowers appear from June to October
  • Cherry-like, green-brown berries are encased within green or black-mottled calyces. Branches of the mature Chinese lantern-style fruits can be dried and used for winter decoration
  • Height to 1.2m (4ft), spread to 1m (3¼ft)
