La cultiver

Propagation
division, seed
When to plant
Spring, Summer
Overwintering
Indoors, protect from frost. Reduce watering slightly in winter and keep in a bright location away from heat sources.
In containers
Grows very well in containers, needing at least a 10-inch pot to accommodate its root system.

Division

  1. Gently remove the plant from its pot.
  2. Locate natural divisions in the root ball.
  3. Carefully separate the divisions with a clean knife or by hand.
  4. Pot each division into its own container with fresh potting mix.
  5. Water lightly and keep in a warm spot with indirect light.

Seed

  1. Sow seeds in a well-draining seed starting mix.
  2. Keep the mix consistently moist and warm (around 70-75°F).
  3. Germination can be slow and erratic, taking several weeks to months.
  4. Transplant seedlings into individual pots once they are large enough to handle.
  5. Provide bright, indirect light and consistent moisture.

Pair with plants that enjoy consistent moisture and bright, indirect light for a harmonious display.
