PropagationPropagation Material: Root Division , Seeds
Description: Can be easily multiplied by rootstock division when the plant is dormant. Be careful, as rhizomes are easily broken. Seeds should be sown on a moist, shaded seed bed immediately after collection. Expect the seedlings to flower in 3-4 years.
Seed Collection: A long, slender pod splits open 4-5 weeks after the bloom period. To catch the seeds, collect the pods when the seeds have turned dark brown and allow the pods to dry and split in a paper bag. Seeds lose viability quickly in storage.
Commercially Avail: yes
Maintenance: A light, leafy winter cover is desirable.
