How to Propagate Rengarenga

Last Updated: November 5, 2020

Rengarenga lilies (Arthropodium cirratum) are easy to propagate. Additional new plants can be placed elsewhere in the garden or given to other people for their gardens.

Steps

1
Propagate through planting seeds. Collect the seeds from the Renga Renga lilies at the end of summer from the ends of the finished tiny white flowers.
- Plant the seeds into a tub of seed raising mix. Don't sow too deeply and only cover lightly.
- Wait anywhere between 10 to 30 days for germination. Keep watered.
- Plant the seedlings in small containers. They're ready for adding to the garden at around 10cm (4 inches) tall.
2
Divide the plant. This method is another way of propagating rengarenga lilies.
- Cut back the leaves about two-thirds of the way. Take out any dead or damaged plant.
- Dig up the whole plant. Use a garden fork to do this. Loosen the roots, then gently move the plant apart. When separating, hold the plant down as low as possible.
- Be sure to keep roots attached to each division.
- Plant into containers or into the garden for new growth.
