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:
A light, leafy winter cover is desirable.
