Aspidistra elatior (Cast Iron Plant or Haran)

Indoors or out, this is a low growing, evergreen leafy thing to 60cm that will survive in frost free shady corners. Look out for the crimson cup shaped flowers occasionally appearing at soil level. In their native Japan, these are pollinated by slugs and fungus gnats.

They hate the sun! Grow in mild, shady gardens or anywhere in the house where nothing else grows because it's too dark. Beloved of the Victorians, they grew it in dark rooms, with dust and pollution from gas lamps and coal fires. Propagated by division.
