The plant usually grows well for me, but did not overwinter last year. I got a new clump from a friend, and started dividing it up, but some of the fans won't stand up when I plant them at the soil level of the original clump. I am beset with questions which the internet does not help answer: How deep should I plant the fans? Can I cut a large fan in half, and do I need to let it callous before planting? Can I use chicken grit or gravel on the soil surface to help the fans stand up without planting it too deeply? Will the fans with flower stalks also grow, or should I just compost them? Any other advice would be appreciated.

This plant self sows very freely. Sometimes too much. Luckily it's easy to remove any you don't want.
Does well in dry areas.

Chilean native herbaceous perennial (rhizome) that can be found on moist locations, at full sun. This plant can reach 1 m height and is a proliferous re-seeder.

Main requirements: full sun and good drainage. Some permanent moisture is desireable. This plant is valued as well for foliage as for its flowers.

Propagation from seeds: stratified sowing during Autumn in a mix of equal parts of compost, regular garden soil and river sand. Transplant once the plantil reaches 5 cm (2"). This plant will bloom first year from seeds. It can also be propagated dividing its rhizoms.

Recommended for borders, to naturalize on a meadow, in flower beds, pots, containers and balconies. Can be used as cut flower.
