True bulbs are very easy to propagate. Nearly all bulbs readily multiply by naturally producing offsets (bulblets) from the parent bulb.
Bulblets can be removed when the bulbs are lifted for storage or when too many bulblets crowd out the plant, reduce overall flowering and the bulbs need separating and replanting.

Step by step
- After digging up the bulbs, carefully detach the small bulblets. What you do next depends on the size of the bulblets.
- Smaller bulblets may take two to four years to flower, but some (such as Cardiocrinum giganteum may take five to seven years.
- Larger bulblets can be replanted in the ground immediately. Small bulblets or those of tender plants should be grown on in pots until they have reached a larger flowering size.
