Aspidistra elatior

  • Cast Iron Plant
  • Bar Room Plant

It survives deep shade, cold rooms, dry air and months of neglect, and it is safe for cats and dogs. The only catch is how slowly it grows.

Aspidistra elatior earned its common name in Victorian parlours, where it survived gas lighting, coal smoke, cold draughts and long stretches of being ignored. Almost nothing else managed it.

It is still the plant to reach for when a spot has defeated everything else.

Light

Aspidistra elatior grows best in low to medium indirect light. It does not merely tolerate shade, it prefers it.

Too much light

Direct sun bleaches the deep green leaves to a washed-out yellow and scorches brown patches into them. This is one of very few houseplants where a bright windowsill is actively the wrong place.

Watering

Water when the top 5cm (2 inches) of soil is dry. Expect that to take a while, particularly in a dim spot.

On average:

  • Spring & summer: every 2 weeks
  • Autumn & winter: every 4-6 weeks

Signs of overwatering

  • Leaves yellow from the base
  • Soft brown patches near soil level
  • Soil stays wet for a long time

Signs of underwatering

  • Leaf tips go brown and dry
  • Leaves lose their gloss

Humidity and temperature

Humidity is irrelevant here. Dry winter air causes no problems.

It handles a very wide temperature range, from about 5°C to 27°C (41-80°F), which makes it usable in unheated hallways and porches where tropical plants would die.

Soil and repotting

Soil

Standard potting compost with a little perlite. Nothing special.

Repotting

Every 4 to 5 years at most. It is extremely slow, dislikes root disturbance, and does better left alone.

Feeding

A balanced liquid fertiliser two or three times over spring and summer is plenty. Nothing in winter.

Pruning and grooming

Cut damaged or yellowed leaves right down at soil level. New leaves come up from the base, so there is no shaping to do.

Wipe the leaves occasionally. They are broad, dark and collect dust visibly.

It is genuinely slow

Aspidistra elatior produces perhaps two or three new leaves in a year. A large specimen takes a decade or more, which is why mature plants are expensive.

Buy it at the size you want it. This is not a plant you grow on.

Common problems

Bleached, yellowing leaves

Too much light. Move it away from the window.

Brown leaf tips

Underwatering, or minerals from tap water.

No new growth

Almost certainly normal. Two or three leaves a year is a healthy rate.

Soft brown patches at the base

Overwatering. This is the only realistic way to kill one.
